     DETAILED DESCRIPTION 
     In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of an embodiment of the present disclosure. It will be evident, however, to one skilled in the art that the present disclosure may be practiced without these specific details. 
     In some example embodiments, a system and method for sharing information on a network-based social platform is illustrated. A request may be received from a first user of a network-based social platform to add an item to a list associated with a second user of the network-based social platform. For example, the item may for sale on a network-based marketplace. The list may include one or more items and facilitate watching the items in real time (e.g., watch list) on the network-based social platform to monitor the progress of an auction or an immediate purchase of the item on the network-based marketplace. Next, in some embodiments, the system may determine whether the first user is authorized to add the item to the list based on a predetermined relationship between the first user and the second user. For example, a predetermined relationship may have been consensually established by the first and second users on the network-based social platform and may, in some embodiments, include the relationship “friend” or “favorite friend.” Finally, the system may communicate the request to the network-based marketplace which, in turn, adds the item to the list associated with the second user. Accordingly, in some embodiments, a first user on a network-based social platform may share information concerning an item available on a network-based marketplace with a second user on a network-based social platform by adding the item to a list used to monitor the item on the network-based social platform. In some embodiments, the second user may block the first user from adding the item to the watch list of the second user. 
     Platform Architecture 
       FIG. 1  is a network diagram depicting a system  10 , according to one embodiment of the present disclosure, having a client-server and a peer-to peer architecture. The system  10  facilitates shopping activity, in the exemplary form of a network-based marketplace  12 , and a network-based social platform  13  that communicate over a network  14 . In one embodiment, the network-based marketplace  12  and the network-based social platform  13  communicate in peer-to peer architecture via programmatic interfaces. Further, the network-based marketplace  12  and the network-based social platform  13  respectively communicate in client-server architecture with clients. The network-based marketplace  12 , provides server-side functionality, via the network  14  (e.g., the Internet), to the one or more client machines  20  and  22 . Similarly, the network-based social platform  13  provides server-side functionality, via the network  14  (e.g., the Internet), to the one or more client machines  20  and  22 .  FIG. 1  illustrates, for example, a web client  16  (e.g., a browser, such as the Internet Explorer browser developed by Microsoft Corporation of Redmond, Washington State), and a programmatic client  18  executing on respective client machines  20  and  22 . 
     Turning specifically to the network-based social platform  13 , an application program interface (API) server  25  and a web server  27  are coupled to, and provide programmatic and web interfaces respectively to, one or more application servers  29 . The application servers  29  may host one or more social applications  31  and a network-based marketplace interface module  33  that communicates with a communication module  39  and a processing module  41 . The application servers  28  are, in turn, shown to be coupled to one or more databases servers  35  that facilitate access to one or more databases  37 . 
     The social applications  31  provide a number of social networking functions and services to users that access the network-based social platform  13 . For example, the social applications  31  may enable a user to store information in a profile that may be viewed at the client machines  20 ,  22  and to selectively grant access to information that appears on the profile to other users who may also view the profile at their client machines  20 ,  22 . The social applications  31  may provide criteria that may be employed by a user to grant various levels of access to various levels of users. For example, a first user may access profile information associated with a second user responsive to the first user achieving the status of “friend” in relation to a second user. A user may achieve the status of friend by accepting an invitation from another user or by sending a request to a user that subsequently grants the request. 
     The social applications  31  may further enable third party service providers to add “applications” on the network-based social platform  13  that are utilized by users to interact with other users. For example, a network-based marketplace application may be added by a third party service provider in the form of the network-based marketplace interface module  33 , the communication module  39 , and the processing module  41  that may provide market application services in the network-based social platform  13  environment and may communicate with the network-based marketplace  12 . 
     In one embodiment, a request related to the marketplace application may be generally processed as follows. The request may originate at the client machines  20 ,  22  that communicates the request via programmatic or web interface services  25 ,  27  to the social applications  31  that, in turn, communicate the request to the network-based marketplace interface module  33  that, in turn, communicates the request to the communication module  39  and processing module  41  that process the request. Conversely, the communication module  39  and processing module  41  may respond to the social applications  31  via the network-based marketplace interface module  33 . In some instances processing of the request may require communication with the network-based marketplace  12 . In such instances the communication module  41  or the processing module  41  may communicate via the API interface  25  with the network-based marketplace  12 . 
     The network-based social platform  13  may be embodied as FACEBOOK® services, a social utility that connects people with friends and others who work, study and live around them provided by Facebook of Palo Alto, Calif. 
     The web client  16 , it will be appreciated, accesses the various social applications  31  via the web interface supported by the web server  27 . Similarly, the programmatic client  18  accesses the various services and functions provided by the social applications  31  via the programmatic interface provided by the API server  25 . 
     Turning to the network-based marketplace  12 , an application program interface (API) server  24  and a web server  26  are coupled to, and provide programmatic and web interfaces respectively to, one or more application servers  28 . The application servers  28  host one or more marketplace applications  30  and payment applications  32 . The application servers  28  are, in turn, shown to be coupled to one or more databases servers  35  that facilitate access to one or more databases  36 . 
     The marketplace applications  30  provide a number of marketplace functions and services to users that access the marketplace  12 . The payment applications  32  likewise provide a number of payment services and functions to users. The payment applications  32  may allow users to quantify for, and accumulate, value (e.g., in a commercial currency, such as the U.S. dollar, or a proprietary currency, such as “points”) in accounts, and then later to redeem the accumulated value for products (e.g., goods or services) that are made available via the marketplace applications  30 . While the marketplace and payment applications  30  and  32  are shown in  FIG. 1  to both form part of the network-based marketplace  12 , it will be appreciated that, in alternative embodiments of the present disclosure, the payment applications  32  may form part of a payment service that is separate and distinct from the marketplace  12 . The network-based marketplace  12  may be embodied as eBAY, the world&#39;s online marketplace, provided by eBay of San Jose, Calif. 
     Further, while the system  10  shown in  FIG. 1  employs a client-server architecture and a peer-to-peer architecture, the present disclosure is of course not limited to such an architecture, and could equally well find application in any combination of client-server, distributed, or peer-to-peer, architecture systems. The various marketplace and payment applications  30  and  32  could also be implemented as standalone software programs, which do not necessarily have networking capabilities. 
     The web client  16 , it will be appreciated, accesses the various marketplace and payment applications  30  and  32  via the web interface supported by the web server  26 . Similarly, the programmatic client  18  accesses the various services and functions provided by the marketplace and payment applications  30  and  32  via the programmatic interface provided by the API server  24 . The programmatic client  18  may, for example, be a seller application (e.g., the TurboLister application developed by eBay Inc., of San Jose, Calif.) to enable sellers to author and manage listings of items on the marketplace  12  in an off-line manner, and to perform batch-mode communications between the programmatic client  18  and the network-based marketplace  12 . 
     It will be appreciated that the marketplace applications  30 , payment applications  32 , social applications  31 , the network-based marketplace interface module  33 , the communication module  39  and the processing module  41  may execute on a single platform. Accordingly, in one embodiment, the aforementioned applications/modules may execute on the network-based marketplace  12  and in another embodiment the aforementioned applications/module may execute on the network-based social platform  13 . 
       FIG. 1  also illustrates a third party application  38 , executing on a third party server machine  40 , as having programmatic access to the network-based marketplace  12  via the programmatic interface provided by the API server  24 . For example, the third party application  38  may, utilizing information retrieved from the network-based marketplace  12 , support one or more features or functions on a website hosted by the third party. The third party website may, for example, provide one or more promotional, marketplace or payment functions that are supported by the relevant applications of the network-based marketplace  12 . 
     Social Platform Applications 
       FIG. 2  is a block diagram illustrating applications that execute on the network-based social platform, according to an embodiment. The network-based social platform applications include news feed applications  47 , profile applications  49 , note applications  51 , forum applications  53 , search applications  55 , relationship applications  57 , network applications  59 , communication applications  61 , account applications  63 , photo applications  65 , event applications  67 , and group applications  69 . 
     The news feed applications  47  publish events associated with the user and friends of the user on the network-based social platform  13 . The news feed applications  47  may publish the events On the user profile of a user. For example, the news feed applications  47  may publish the uploading of a photo album by one user on the user profile the user and the user profiles of friends of the user. 
     The profile applications  49  may maintain user profiles for each of the users on the network-based social platform  13 . Further, the profile applications  49  may enable a user to restrict access to selected parts of their profile to prevent viewing by other users. The notes applications  51  may be used to author notes that may be published on various user interfaces. 
     The forum applications  53  may maintain a forum for users to post comments and display the forum via the profile associated with a user. The user may add comments to the forum, remove comments from the forum and restrict visibility to other users. In addition, other users may post comments to the forum. The search applications  55  may enable a user to perform a keyword search for users, groups, and events. In addition, the search applications  55  may enable a user to search for content (e.g. favorite movies) on profiles accessible to the user. 
     The relationship applications  57  may maintain relationship information for the users. The network applications  59  may facilitate the addition of social networks by a user, the social networks based on a school, workplace, or region or any social construct for which the user may prove an affiliation. The communication applications  61  may process incoming and outgoing messages, maintain an inbox for each user, facilitate sharing of content, facilitate interaction among friends (e.g., poking), process requests, process events, process group invitations and process communicating notifications. 
     The account applications  63  may provide services to facilitate registering, updating, and deleting user accounts. The photo applications  65  may provide services to upload photographs, arrange photographs, set privacy options for albums and tag photographs with text strings. The event applications  67  provide services to create events, review upcoming events, and review past events. The group applications  69  may be used to maintain group information, display group information, and navigate to groups. 
       FIG. 3  is a block diagram illustrating a database  37 , according to an embodiment, at a network-based social platform  13 . The database  37  is shown to include social platform user profile information  42  that stores user profile information for each user on the network-based social platform  13 . The user profile information  42  may include information related to the user and specifically may include relationship information  43  and block information  45 . The relationship information  43  may store a predetermined relationship between the user associated with the user profile information  42  and other users on the network-based social platform  13 . For example, a first user, may be designated a “friend,” or “favourite friend,” etc. with a second user, the first user associated with the user profile information  42  and the respective designations associated with increasing levels of disclosure between the first user and second user. The block information  45  may store a configured preference of the user to block the addition of an item by other users to the watch list associated with the user. 
     Marketplace and Payment Applications 
       FIG. 4  is a block diagram illustrating multiple marketplace and payment applications  30 ,  32  that, in one exemplary embodiment of the present disclosure, are provided as part of the network-based marketplace  12 . The marketplace  12  may provide a number of listing and price-setting mechanisms whereby a seller may list goods or services for sale, a buyer can express interest in or indicate a desire to purchase such goods or services, and a price can be set for a transaction pertaining to the goods or services. To this end, the marketplace applications  30  are shown to include one or more auction applications  44  which support auction-format listing and price setting mechanisms (e.g., English, Dutch, Vickrey, Chinese, Double, Reverse auctions etc.). The various auction applications  44  may also provide a number of features in support of such auction-format listings, such as a reserve price feature whereby a seller may specify a reserve price in connection with a listing and a proxy-bidding feature whereby a bidder may invoke automated proxy bidding. 
     A number of fixed-price applications  46  support fixed-price listing formats (e.g., the traditional classified advertisement-type listing or a catalogue listing) and buyout-type listings. Specifically, buyout-type listings (e.g., including the Buy-It-Now (BIN) technology developed by eBay Inc., of San Jose, Calif.) may be offered in conjunction with an auction-format listing, and allow a buyer to purchase goods or services, which are also being offered for sale via an auction, for a fixed-price that is typically higher than the starting price of the auction. 
     Store applications  48  allow sellers to group their listings within a “virtual” store, which may be branded and otherwise personalized by and for the sellers. Such a virtual store may also offer promotions, incentives and features that are specific and personalized to a relevant seller. 
     Reputation applications  50  allow parties that transact utilizing the network-based marketplace  12  to establish, build, and maintain reputations, which may be made available and published to potential trading partners. Consider that where, for example, the network-based marketplace  12  supports person-to-person trading, users may have no history or other reference information whereby the trustworthiness and credibility of potential trading partners may be assessed. The reputation applications  50  allow a user, for example through feedback provided by other transaction partners, to establish a reputation within the network-based marketplace  12  over time. Other potential trading partners may then reference such a reputation for the purposes of assessing credibility and trustworthiness. 
     Personalization applications  52  allow users of the marketplace  12  to personalize various aspects of their interactions with the marketplace  12 . For example a user may, utilizing an appropriate personalization application  52 , create a personalized reference page at which information regarding transactions to which the user is (or has been) a party may be viewed. Further, a personalization application  52  may enable a user to personalize listings and other aspects of their interactions with the marketplace  12  and other parties. 
     In one embodiment, the network-based marketplace  12  may support a number of marketplaces that are customized, for example, for specific geographic regions. A version of the marketplace  12  may be customized for the United Kingdom, whereas another version of the marketplace  12  may be customized for the United States. Each of these versions may operate as an independent marketplace, or may be customized (or internationalized) presentations of a common underlying marketplace by internationalization application  54 . 
     Navigation of the network-based marketplace  12  may be facilitated by one or more navigation applications  56 . For example, a search application enables key word searches of listings published via the marketplace  12 . A browse application allows users to browse various category, catalogue, or inventory data structures according to which listings may be classified within the marketplace  12 . Various other navigation applications may be provided to supplement the search and browsing applications. 
     In order to make listings, available via the network-based marketplace  12 , as visually informing and attractive as possible, the marketplace applications  30  may include one or more imaging applications  58  utilizing which users may upload images for inclusion within listings. An imaging application  58  also operates to incorporate images within viewed listings. The imaging applications  58  may also support one or more promotional features, such as image galleries that are presented to potential buyers. For example, sellers may pay an additional fee to have an image included within a gallery of images for promoted items. 
     Listing creation applications  60  allow sellers conveniently to author listings pertaining to goods or services that they wish to transact via the marketplace  12 , and listing management applications  62  to allow sellers to manage such listings. Specifically, where a particular seller has authored and/or published a large number of listings, the management of such listings may present a challenge. The listing management applications  62  provide a number of features (e.g., auto-relisting, inventory level monitors, etc.) to assist the seller in managing such listings. One or more post-listing management applications  64  also assist sellers with a number of activities that typically occur post-listing. For example, upon completion of an auction facilitated by one or more auction applications  44 , a seller may wish to leave feedback regarding a particular buyer. To this end, a post-listing management application  64  may provide an interface to one or more reputation applications  50 , so as to allow the seller conveniently to provide feedback regarding multiple buyers to the reputation applications  50 . In addition, the post listing management applications  64  may facilitate tracking and organization of listings for a user by maintaining identified listings in lists. For example, the lists may include watch information in the form of identified items that are offered for sale on the network-based marketplace  12 . 
     Dispute resolution applications  66  provide mechanisms whereby disputes arising between transacting parties may be resolved. For example, the dispute resolution applications  66  may provide guided procedures whereby the parties are guided through a number of steps in an attempt to settle a dispute. In the event that the dispute cannot be settled via the guided procedures, the dispute may be escalated to a third party mediator or arbitrator. 
     A number of fraud prevention applications  68  implement various fraud detection and prevention mechanisms to reduce the occurrence of fraud within the marketplace  12 . 
     Messaging applications  70  are responsible for the generation and delivery of messages to users of the network-based marketplace  12 , such messages for example advising users regarding the status of listings at the marketplace  12  (e.g., providing “outbid” notices to bidders during an auction process or to provide promotional and merchandising information to users). 
     Merchandising applications  72  support various merchandising functions that are made available to sellers to enable sellers to increase sales via the marketplace  12 . The merchandising applications  80  also operate the various merchandising features that may be invoked by sellers, and may monitor and track the success of merchandising strategies employed by sellers. 
     The network-based marketplace  12  itself, or one or more parties that transact via the marketplace  12 , may operate loyalty programs that are supported by one or more loyalty/promotions applications  74 . For example, a buyer may earn loyalty or promotions points for each transaction established and/or concluded with a particular seller, and be offered a reward for which accumulated loyalty points can be redeemed. 
     Data Structures 
       FIG. 5  is a high-level entity-relationship diagram, illustrating various tables  90  that may be maintained within the databases  36 , and that are utilized by and support the marketplace and payment applications  30  and  32 . A user table  92  contains a record for each registered user of the network-based marketplace  12 , and may include identifier, address and financial instrument information pertaining to each such registered user. A user may, it will be appreciated, operate as a seller, a buyer, or both, within the network-based marketplace  12 . In one exemplary embodiment of the present disclosure, a buyer may be a user that has accumulated value (e.g., commercial or proprietary currency), and is then able to exchange the accumulated value for items that are offered for sale by the network-based marketplace  12 . 
     The tables  90  also include an items table  94  in which are maintained item records (e.g., item information) for goods and services that are available to be, or have been, transacted via the marketplace  12 . Each item record within the items table  94  may furthermore be linked to one or more user records within the user table  92 , so as to associate a seller and one or more actual or potential buyers with each item record. 
     A transaction table  96  contains a record for each transaction (e.g., a purchase transaction) pertaining to items for which records exist within the items table  94 . An order table  98  is populated with order records, each order record being associated with an order. Each order, in turn, may be with respect to one or more transactions for which records exist within the transactions table  96 . 
     Bid records within a bids table  100  each relate to a bid received at the network-based marketplace  12  in connection with an auction-format listing supported by an auction application  44 . A feedback table  102  is utilized by one or more reputation applications  50 , in one exemplary embodiment, to construct and maintain reputation information concerning users. In one embodiment, the reputation information may include feedback records associated with transactions. A history table  104  maintains a history of transactions to which a user has been a party. One or more attributes tables  106  record attribute information pertaining to items for which records exist within the items table  94 . Considering only a single example of such an attribute, the attributes tables  106  may indicate a currency attribute associated with a particular item, the currency attribute identifying the currency of a price for the relevant item as specified in by a seller. 
       FIG. 6  is a block diagram illustrating a user table  92 , according to an embodiment. The user table  92  includes a user information entry  160  for each user on the network-based marketplace  12 . Each user information entry  160  may specifically include watch information  162 . The watch information  162  includes item identifiers that correspond to items for sale on the network-based marketplace  12  (e.g., watch list). For example, the user may be interested in a listing for a book that is currently being auctioned. To monitor the sale of the book the user may add the book to the watch list associated with the user. In addition, the user may add the item to the watch list of another user. 
       FIG. 7  is a block diagram illustrating an items table  94 , according to an embodiment. The items table  94  includes item information  170  for each item on the network-based marketplace  12 . For example, the item information  170  may store a title, a description, a photograph, or any other information or content descriptive of goods or services that may be offered for sale on the network-based marketplace  12 . The item information  170  is specifically shown to include auction information  172  and purchase information  174 . The auction information  172  may include information related to the auctioning of the item (e.g., minimum bid, current bid, highest bid, start time of auction, end time of auction, etc.). The purchase information  174  may include information related to the purchase of the item (e.g., purchase price). In one embodiment, an item offered for sale on the network-based marketplace  12  may be acquired by submitting the highest bid in an auction or by paying a predetermined purchase price. 
       FIG. 8  is a block diagram illustrating a method  180 , according to an embodiment, to add an item for sale on a network-based marketplace to a list of another user on a network-based social platform. Illustrated on the right is the network-based marketplace  12 . Illustrated in the middle is the network-based social platform  13  and illustrated on the left is the client machine  20 . 
     A first user may have searched for iPhones offered for sale on the network-based marketplace  12  by using a search facility provided by the marketplace application on the network-based social platform  13 . After identifying an iPhone of particular interest in the search results, the method  180  may commence, at operation  182 , with the first user requesting the iPhone (e.g., item) be added to the watch list of a second user on the network-based social platform  13 . At operation  184 , at the network-based social platform  13 , the request may be received by the social applications  31  that forward the request to the network-based marketplace interface module  33  that forwards the request to the communication module  39 . 
     At decision operation  186 , the processing module  41  may determine whether the user is authorized to add the item to the list associated with the second user. For example, the processing module  41  may determine whether relationship information  43  for the first user identifies a predetermined relationship with the second user as being a “friend” or a “favourite friend.” If the second user is determined to be a “friend” or a “favourite friend” then a branch is made to decision operation  188 . Otherwise processing ends. 
     At decision operation  188 , the processing module  41  determines whether the second user has blocked the addition of items to the list (e.g., watch list) associated with the second user. For example, the processing module  41  may determine whether block information  45  associated with the second user prohibits addition of items to the list of the second user. If the block information  45  blocks additions to the list then processing ends. Otherwise processing continues at operation  190 . At operation  190 , the communication module  39  communicates the request to add the iPhone to the network-based marketplace  12 . 
     At operation  192 , the network-based marketplace  12  receives the request to add the iPhone and at operation  194  the network-based marketplace  12  adds the corresponding item identifier to the watch list associated with the second user. For example, the network-based marketplace  12  may store the item identifier in the watch information  162  associated with the second user. 
       FIG. 9  is a block diagram illustrating a method  200 , according to an embodiment, to block the addition of an item to a list. Illustrated on the right is the network-based marketplace  12 . Illustrated in the middle is the network-based social platform  13  and illustrated on the left is the client machine  20 . The method  200  commences at operation  202  with the user at the client machine  20  requesting that additions of items to the watch list associated with the user be blocked. 
     At operation  204 , at the network-based social platform  13 , the request is received by the social applications  31  that forward the request to the network-based marketplace interface module  33  that forwards the request to the communication module  39 . At operation  206  the processing module stores the request to block additions for the user and processing ends. For example, the processing module  41  may store the request in the block information  45  associated with the user. In another embodiment, the block information  45  may be stored as user information  160  at the network-based marketplace  12 . 
       FIG. 10  is a block diagram illustrating a method  220 , according to an embodiment, to display a list. Illustrated on the right is the network-based marketplace  12 . Illustrated in the middle is the network-based social platform  13  and illustrated on the left is the client machine  20 . The method  220  commences at operation  222  with the user at the client machine  20  requesting their watch list to be displayed. 
     At operation  224 , at the network-based social platform  13 , the request is received by the social applications  31  that forward the request to the network-based marketplace interface module  33  that forwards the request to the communication module  39  and at operation  226 , the communication module  39  forwards the request to the network-based marketplace  12 . 
     At operation  228 , the network-based marketplace  12  receives the request and at operation  230  the network-based marketplace  12  communicates the requested items to the network-based social platform  13 . For example, the network-based marketplace  12  may retrieve the item identifiers from the watch information  162  associated with the requesting user. 
     At operation  232 , the communication module  39 , at the network-based social platform  13 , receives the item identifiers and at operation  234  the communication module  39  may communicate a user interface that includes the items (e.g., watch list) to the social applications  31  that, in turn, communicate the user interface that includes the requested items (e.g., watch list), via the web interface  27 , to the client machine  20  where it is displayed at operation  236 . 
       FIG. 11  is a diagram illustrating a user interface  250 , according to an embodiment. The user interface  250  displays search results that were generated in response to a user entering a search request (e.g., keyword) received by the network-based social platform  13 . The user interface  250  includes user interface elements  252  that relate a description of the user that requested the search, the keywords entered by the user (e.g., iPhones), and a count of search results. For example, “John Doe” requested a search for “iPhones” and received search results including 123455 items. Further, the user interface  250  includes search results  254  in the form of user interface elements  256  that respectively correspond to items. Each user interface element  256  includes a user interface elements  258 ,  260 , and  262 . The user interface element  258  may be selected to add the corresponding item to the watch list associated with the user that requested the search results (e.g., John Doe). The user interface element  260  may be selected to add the item to the watch list of one or more user, as illustrated on  FIG. 12 . The user interface element  262  may be selected to view the item on a user interface that is served by the network-based marketplace  12 . The user interface served by the network-based marketplace  12  may for example include item information  170  describing the item, auction information  112  that enables the user to enter a bid in an auction of the item, and purchase information  174  that enables the user to purchase the item. 
       FIG. 12  is a diagram illustrating a user interface  270 , according to an embodiment. The user interface  270  includes user interface elements  272  that describes the identity of the present user (e.g., John Doe) from the point of view of the network-based social platform  13  based on, for example, a user name and password. The user interface  270  further includes user interface elements  274  that describe a item (e.g., iPhone) for sale on the network-based marketplace  12 , and user interface elements  276  that respectively correspond to “friends” of the user (e.g., John Doe). 
     The user interface elements  278  may be selected to click through to the network-based marketplace  12  and purchase the item (e.g., iPhone) on the user interface  270 . 
     Each user interface element  276  may include user interface elements  280 ,  282  and  284 . The user interface element  280  may be an image representing a user on the network-based social platform  13  and the user interface element  282  may be the name of the user. The user interface element  284  maybe a checkbox that may be selected to add the item to the watch list(s) of the identified user(s). Further, a single request to add the item may be associated multiple selected checkboxes. Accordingly, selection of checkboxes associated with a first and second user may result in the addition of the identified item to the watch lists of the first and second user responsive to a selection of the user interface element  288 . Further, the user interface element  282  may be selected to view the watch list associated with the identified user. 
     The user interface  270  further includes an input box  286  to receive an alphanumeric string, such as a personal note, from the first user (e.g., John Doe). The processing module  41  may receive the alphanumeric string and associate the alphanumeric string with the item (e.g., shopping information) on the watch lists identified via the checkboxes  284 . 
       FIG. 13  is a diagram illustrating a user interface  290 , according to an embodiment. The user interface  290  includes user interface elements  292  that describes the identity of the present user (e.g., Jane Doe) from the point of view of the network-based social platform  13  based on, for example, a user name and password. The user interface  290  further includes user interface elements  294  that may be a count of items on the watch list of the present user (e.g., Jane Doe), and one or more user interface elements  296  respectively describing items (e.g., iPhone) being watched. Each user interface element  296  may include a note  298  associated with an alphanumeric string from another user that added the item to the watch list. In one embodiment the note may be displayed only to the owner (e.g., Jane Doe) of the watch list. Each user interface element may further include a user interface element  300  that may be selected to click through to the network-based marketplace  12  and purchase the item or enter a bid for the item. 
       FIG. 14  is a diagram illustrating a user interface  310 , according to an embodiment, to block adding items to a watch list. The user interface  310  may include mutually exclusive checkboxes  312  and  314  to respectively unblock or block the addition of items to the watch list of the user (e.g., Jane Doe). 
       FIG. 15  is a diagram illustrating a user interface  320 , according to an embodiment, of a user profile. The user profile  320  may include user profile information  42  for the user featured by the user profile. All user profile information  42  may be displayed to the user featured by the profile (e.g., Joe Doe). A portion of the user profile information  42  may be displayed to others users according to a status (e.g., “friend,” “favorite friend”). The profile information  42  includes user information  324 , event information  326 , related user information  328  and posted information  330 . 
     The user information  324  includes information about the user. The event information  326  includes events  327  that may be of interest to the user. In one embodiment an event may be an action performed by a “friend” or “favorite friend” of the user. For example, the event information  326  may include an event  327  that describes the addition of an item by a friend “John Doe” to a watch list of a friend “Jane Doe.” Each event  327  may include a user interface element  329  that may be selected to add the item to the watch list of the user associated with the profile (e.g., “Joe Doe”) and a user interface element  331  that may be selected to author a message that is communicated to the user that added the item (e.g., “John Doe”). 
       FIG. 16  is a diagrammatic representation of a machine in the example form of a computer system  1000  within which a set of instructions, for causing the machine to perform any one or more of the methodologies discussed herein, may be executed. In alternative embodiments, the machine operates as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine may operate in the capacity of a server or a client machine in server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine may be a server computer, a client computer, a personal computer (PC), a tablet PC, a set-top box (STB), a Personal Digital Assistant (PDA), a cellular telephone, a web appliance, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine. Further, while only a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein. 
     The example computer system  1000  includes a processor  1002  (e.g., a central processing unit (CPU) a graphics processing unit (GPU) or both), a main memory  1004  and a static memory  1006 , which communicate with each other via a bus  1008 . The computer system  1000  may further include a video display unit  1010  (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)). The computer system  1000  also includes an alphanumeric input device  1012  (e.g., a keyboard), a cursor control device  1014  (e.g., a mouse), a disk drive unit  1016 , a signal generation device  1018  (e.g., a speaker) and a network interface device  1020 . 
     The disk drive unit  1016  includes a machine-readable medium  1022  on which is stored one or more sets of instructions (e.g., software  1024 ) embodying any one or more of the methodologies or functions described herein. The software  1024  may also reside, completely or at least partially, within the main memory  1004  and/or within the processor  1002  during execution thereof by the computer system  1000 , the main memory  1004  and the processor  1002  also constituting machine-readable media. 
     The software  1024  may further be transmitted or received over a network  1026  via the network interface device  1020 . 
     While the machine-readable medium  1022  is shown in an example embodiment to be a single medium, the term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “machine-readable medium” shall also be taken to include any medium that is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the present disclosure. The term “machine-readable medium” shall accordingly be taken to include, but not be limited to, solid-state memories, optical and magnetic media, and carrier wave signals. 
     A Three-Tier Architecture 
     In some embodiments, a method is illustrated as implemented in a distributed or non-distributed software application designed under a three-tier architecture paradigm, whereby the various components of computer code that implement this method may be categorized as belonging to one or more of these three tiers. Some embodiments may include a first tier as an interface (e.g., an interface tier) that is relatively free of application processing. Further, a second tier may be a logic tier that performs application processing in the form of logical/mathematical manipulations of data inputted through the interface level, and communicates the results of these logical/mathematical manipulations to the interface tier, and/or to a backend, or storage tier. These logical/mathematical manipulations may relate to certain business rules, or processes that govern the software application as a whole. A third, storage tier, may be a persistent storage medium or, non-persistent storage medium. In some cases, one or more of these tiers may be collapsed into another, resulting in a two-tier architecture, or even a one-tier architecture. For example, the interface and logic tiers may be consolidated, or the logic and storage tiers may be consolidated, as in the case of a software application with an embedded database. This three-tier architecture may be implemented using one technology, or, as will be discussed below, a variety of technologies. This three-tier architecture, and the technologies through which it is implemented, may be executed on two or more computer systems organized in a server-client, peer to peer, or so some other suitable configuration. Further, these three tiers may be distributed between more than one computer system as various software components. 
     Modules, Components and Logic 
     Certain embodiments are described herein as including logic or a number of modules, components or mechanisms. A module, logic, component or mechanism (herein after collectively referred to as a “module”) may be a tangible unit capable of performing certain operations and is configured or arranged in a certain manner. In example embodiments, one or more computer systems (e.g., a standalone, client or server computer system) or one or more components of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a “module” that operates to perform certain operations as described herein. 
     In various embodiments, a “module” may be implemented mechanically or electronically. For example, a module may comprise dedicated circuitry or logic that is permanently configured (e.g., within a special-purpose processor) to perform certain operations. A module may also comprise programmable logic or circuitry (e.g., as encompassed within a general-purpose processor or other programmable processor) that is temporarily configured by software to perform certain operations. It will be appreciated that the decision to implement a module mechanically, in the dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations. 
     Accordingly, the term “module” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired) or temporarily configured (e.g., programmed) to operate in a certain manner and/or to perform certain operations described herein. Considering embodiments in which modules or components are temporarily configured (e.g., programmed), each of the modules or components need not be configured or instantiated at any one instance in time. For example, where the modules or components comprise a general-purpose processor configured using software, the general-purpose processor may be configured as respective different modules at different times. Software may accordingly configure the processor to constitute a particular module at one instance of time and to constitute a different module at a different instance of time. 
     Modules can provide information to, and receive information from, other modules. Accordingly, the described modules may be regarded as being communicatively coupled. Where multiple of such modules exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) that connect the modules. In embodiments in which multiple modules are configured or instantiated at different times, communications between such modules may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple modules have access. For example, a one module may perform an operation, and store the output of that operation in a memory device to which it is communicatively coupled. A further module may then, at a later time, access the memory device to retrieve and process the stored output. Modules may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information). 
     Component Design 
     Some example embodiments may include the above illustrated tiers, and processes or operations that make them up, as being written as one or more software components. Common too many of these components is the ability to generate, use, and manipulate data. These components, and the functionality associated with each, may be used by client, server, or peer computer systems. These various components may be implemented by a computer system on an as-needed basis. These components may be written in an object-oriented computer language such that a component oriented, or object-oriented programming technique can be implemented using a Visual Component Library (VCL), Component Library for Cross Platform (CLX), Java Beans (JB), Java Enterprise Beans (EJB), Component Object Model (COM), Distributed Component Object Model (DCOM), or other suitable technique. These components may be linked to other components via various Application Programming interfaces (APIs), and then compiled into one complete server, client, and/or peer software application. Further, these APIs may be able to communicate through various distributed programming protocols as distributed computing components. 
     Distributed Computing Components and Protocols 
     Some example embodiments may include remote procedure calls being used to implement one or more of the above illustrated components across a distributed programming environment as distributed computing components. For example, an interface component (e.g., an interface tier) may reside on a first computer system that is remotely located from a second computer system containing a logic component (e.g., a logic tier). These first and second computer systems may be configured in a server-client, peer-to-peer, or some other suitable configuration. These various components may be written using the above illustrated object-oriented programming techniques, and can be written in the same programming language, or a different programming language. Various protocols may be implemented to enable these various components to communicate regardless of the programming language used to write these components. For example, an component written in C++ may be able to communicate with another component written in the Java programming language through utilizing a distributed computing protocol such as a Common Object Request Broker Architecture (CORBA), a Simple Object Access Protocol (SOAP), or some other suitable protocol. Some embodiments may include the use of one or more of these protocols with the various protocols outlined in the OSI model, or TCP/IP protocol stack model for defining the protocols used by a network to transmit data. 
     A System of Transmission Between a Server and Client 
     Some embodiments may utilize the OSI model or TCP/IP protocol stack model for defining the protocols used by a network to transmit data. In applying these models, a system of data transmission between a server and client, or between peer computer systems is illustrated as a series of roughly five layers comprising: an application layer, a transport layer, a network layer, a data link layer, and a physical layer. In the case of software having a three tier architecture, the various tiers (e.g., the interface, logic, and storage tiers) reside on the application layer of the TCP/IP protocol stack. In an example implementation using the TCP/IP protocol stack model, data from an application residing at the application layer is loaded into the data load field of a TCP segment residing at the transport layer. This TCP segment also contains port information for a recipient software application residing remotely. This TCP segment is loaded into the data load field of an IP datagram residing at the network layer. Next, this IP datagram is loaded into a frame residing at the data link layer. This frame is then encoded at the physical layer, and the data transmitted over a network such as an internet, Local Area Network (LAN), Wide Area Network (WAN), or some other suitable network. In some cases, internet refers to a network of networks. These networks may use a variety of protocols for the exchange of data, including the aforementioned TCP/IP, and additionally ATM, SNA, SDI, or some other suitable protocol. These networks may be organized within a variety of topologies (e.g., a star topology), or structures.
