     BACKGROUND 
     Many users may consume content through user interfaces, such as a video accessible through a video interface. For example, the video may comprise a movie, a television show, a live stream of a sporting event, a webcast, prerecorded video, etc. Users that are watching the video may be provided with a chat room interface through which the users may interact while watching the video. For example, the users may discuss the video with other users within the chat room by writing and reading messages through the chat room interface. 
     The chat room may grow to a significant number of users as more users watch the video (e.g., thousands of users may be within a chat room for discussing an e-sporting event video stream). Unfortunately, the chat room may become overwhelming to the point that users are unable to have meaningful interactions. Users may be unable to single out and/or participate in a certain conversation because text of the chat room may scroll too fast. Thus, users may become overwhelmed, and the chat room may become useless. Also, the chat room interface may experience performance issues such as lag due to resource strain, such as bandwidth consumption and client device resource consumption, from attempting to keep the chat room interface up-to-date with all the messages being generated by the thousands of users. 
     SUMMARY 
     In accordance with the present disclosure, one or more computing devices and/or methods for hosting virtual chat rooms for a chat room are provided. In an example, users that are accessing video interfaces, hosting a video, and chat room interfaces associated with a chat room for the video may be identified (e.g., 3,000 users may be watching a live stream of a sporting event through a webpage comprising a video interface for the live stream and a chat interface for a chat room through which the users may communicate about the sporting event). Signals, associated with the users, may be evaluated to identify user properties of the users. For example, user account data (e.g., a user may log into a service through which the video is provided), social network profile data (e.g., a user age, a user home location, a user demographic, an interest of the user such as in soccer, a career of the user such as a soccer coach, a social network post with an image about a restaurant, etc.), a current location of a user device, how a user previously interact with chat rooms (e.g., a user tends to write 0.06 messages per minute and thus is a passive participant; a user tends to write 2 messages per minute and thus is an active participant; a user tends to get into arguments with other users; etc.), keywords or grammar used by a user (e.g., the user uses a lot of exclamation points, the user tends to use profanity, the user tends to write incomplete sentences or phrases, etc.), a contact list of a user (e.g., the user may desire to be within a virtual chat room with other friends or contacts), and/or a variety of other signals may be used to identify user properties indicative of how the user may interact with other users within a virtual chat room (e.g., the user may be a passive participant that uses proper grammar and tends to interact well with adults). 
     The chat room may be sharded (e.g., partitioned) into a set of virtual chat rooms. For example, the chat room may be sharded and/or users may be assigned to virtual chat rooms based upon a virtual chat room occupancy metric (e.g., a maximum number of occupants for a virtual chat room may be set to 100 users or any other number of users so that users can have meaningful conversations without being overwhelmed) and/or based upon percentages of active participants and passive participants (e.g., a virtual chat room may be defined to have a composition of about 10% or any other percentage of active participants and about 90% or any other percentage of passive participants so that the virtual chat room is not overwhelmed with messages from too many active participants and is not too quiet from too many passive participants). 
     Users may be assigned to virtual chat rooms of the set of virtual chat rooms based upon the user properties. For example, users may be assigned to a virtual chat room so that the virtual chat room has no more than 100 users and has a composition of about 10% or any other percentage of active participants and about 90% or any other percentage of passive participants. In an example, if a first user and a second user previously interacted with one another in a chat room, then the first user and the second user may be assigned to the same virtual chat room. In another example, if a first user and a second user are similar in age or location, then the first user and the second user may be assigned to the same virtual chat room. In another example, users with similar grammar usage (e.g., the user of complete sentences or incomplete sentences, the use of certain keywords, the use of proper grammar or not, the user of statements that invoke a lot or a little reaction, the use of long or short statements, the user of emoticons or exclamation marks, etc.) may be assigned to the same virtual chat room. In this way, users may be assigned to virtual chat rooms to provide a chat room composition that facilitates meaningful and interactive conversations between users. Users may be provided with access to their assigned virtual chat rooms through the chat room interfaces (e.g., messages displayed through a chat room interface may be filtered to message of other users assigned to the same virtual chat room).

     DETAILED DESCRIPTION 
     Subject matter will now be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific example embodiments. This description is not intended as an extensive or detailed discussion of known concepts. Details that are known generally to those of ordinary skill in the relevant art may have been omitted, or may be handled in summary fashion. 
     The following subject matter may be embodied in a variety of different forms, such as methods, devices, components, and/or systems. Accordingly, this subject matter is not intended to be construed as limited to any example embodiments set forth herein. Rather, example embodiments are provided merely to be illustrative. Such embodiments may, for example, take the form of hardware, software, firmware or any combination thereof. 
     1. Computing Scenario 
     The following provides a discussion of some types of computing scenarios in which the disclosed subject matter may be utilized and/or implemented. 
     1.1. Networking 
       FIG. 1  is an interaction diagram of a scenario  100  illustrating a service  102  provided by a set of servers  104  to a set of client devices  110  via various types of networks. The servers  104  and/or client devices  110  may be capable of transmitting, receiving, processing, and/or storing many types of signals, such as in memory as physical memory states. 
     The servers  104  of the service  102  may be internally connected via a local area network  106  (LAN), such as a wired network where network adapters on the respective servers  104  are interconnected via cables (e.g., coaxial and/or fiber optic cabling), and may be connected in various topologies (e.g., buses, token rings, meshes, and/or trees). The servers  104  may be interconnected directly, or through one or more other networking devices, such as routers, switches, and/or repeaters. The servers  104  may utilize a variety of physical networking protocols (e.g., Ethernet and/or Fiber Channel) and/or logical networking protocols (e.g., variants of an Internet Protocol (IP), a Transmission Control Protocol (TCP), and/or a User Datagram Protocol (UDP). The local area network  106  may include, e.g., analog telephone lines, such as a twisted wire pair, a coaxial cable, full or fractional digital lines including T1, T2, T3, or T4 type lines, Integrated Services Digital Networks (ISDNs), Digital Subscriber Lines (DSLs), wireless links including satellite links, or other communication links or channels, such as may be known to those skilled in the art. The local area network  106  may be organized according to one or more network architectures, such as server/client, peer-to-peer, and/or mesh architectures, and/or a variety of roles, such as administrative servers, authentication servers, security monitor servers, data stores for objects such as files and databases, business logic servers, time synchronization servers, and/or front-end servers providing a user-facing interface for the service  102 . 
     Likewise, the local area network  106  may comprise one or more sub-networks, such as may employ differing architectures, may be compliant or compatible with differing protocols and/or may interoperate within the local area network  106 . Additionally, a variety of local area networks  106  may be interconnected; e.g., a router may provide a link between otherwise separate and independent local area networks  106 . 
     In the scenario  100  of  FIG. 1 , the local area network  106  of the service  102  is connected to a wide area network  108  (WAN) that allows the service  102  to exchange data with other services  102  and/or client devices  110 . The wide area network  108  may encompass various combinations of devices with varying levels of distribution and exposure, such as a public wide-area network (e.g., the Internet) and/or a private network (e.g., a virtual private network (VPN) of a distributed enterprise). 
     In the scenario  100  of  FIG. 1 , the service  102  may be accessed via the wide area network  108  by a user  112  of one or more client devices  110 , such as a portable media player (e.g., an electronic text reader, an audio device, or a portable gaming, exercise, or navigation device); a portable communication device (e.g., a camera, a phone, a wearable or a text chatting device); a workstation; and/or a laptop form factor computer. The respective client devices  110  may communicate with the service  102  via various connections to the wide area network  108 . As a first such example, one or more client devices  110  may comprise a cellular communicator and may communicate with the service  102  by connecting to the wide area network  108  via a wireless local area network  106  provided by a cellular provider. As a second such example, one or more client devices  110  may communicate with the service  102  by connecting to the wide area network  108  via a wireless local area network  106  provided by a location such as the user&#39;s home or workplace (e.g., a WiFi (Institute of Electrical and Electronics Engineers (IEEE) Standard 802.11) network or a Bluetooth (IEEE Standard 802.15.1) personal area network). In this manner, the servers  104  and the client devices  110  may communicate over various types of networks. Other types of networks that may be accessed by the servers  104  and/or client devices  110  include mass storage, such as network attached storage (NAS), a storage area network (SAN), or other forms of computer or machine readable media. 
     1.2. Server Configuration 
       FIG. 2  presents a schematic architecture diagram  200  of a server  104  that may utilize at least a portion of the techniques provided herein. Such a server  104  may vary widely in configuration or capabilities, alone or in conjunction with other servers, in order to provide a service such as the service  102 . 
     The server  104  may comprise one or more processors  210  that process instructions. The one or more processors  210  may optionally include a plurality of cores; one or more coprocessors, such as a mathematics coprocessor or an integrated graphical processing unit (GPU); and/or one or more layers of local cache memory. The server  104  may comprise memory  202  storing various forms of applications, such as an operating system  204 ; one or more server applications  206 , such as a hypertext transport protocol (HTTP) server, a file transfer protocol (FTP) server, or a simple mail transport protocol (SMTP) server; and/or various forms of data, such as a database  208  or a file system. The server  104  may comprise a variety of peripheral components, such as a wired and/or wireless network adapter  214  connectable to a local area network and/or wide area network; one or more storage components  216 , such as a hard disk drive, a solid-state storage device (SSD), a flash memory device, and/or a magnetic and/or optical disk reader. 
     The server  104  may comprise a mainboard featuring one or more communication buses  212  that interconnect the processor  210 , the memory  202 , and various peripherals, using a variety of bus technologies, such as a variant of a serial or parallel AT Attachment (ATA) bus protocol; a Uniform Serial Bus (USB) protocol; and/or Small Computer System Interface (SCI) bus protocol. In a multibus scenario, a communication bus  212  may interconnect the server  104  with at least one other server. Other components that may optionally be included with the server  104  (though not shown in the schematic architecture diagram  200  of  FIG. 2 ) include a display; a display adapter, such as a graphical processing unit (GPU); input peripherals, such as a keyboard and/or mouse; and a flash memory device that may store a basic input/output system (BIOS) routine that facilitates booting the server  104  to a state of readiness. 
     The server  104  may operate in various physical enclosures, such as a desktop or tower, and/or may be integrated with a display as an “all-in-one” device. The server  104  may be mounted horizontally and/or in a cabinet or rack, and/or may simply comprise an interconnected set of components. The server  104  may comprise a dedicated and/or shared power supply  218  that supplies and/or regulates power for the other components. The server  104  may provide power to and/or receive power from another server and/or other devices. The server  104  may comprise a shared and/or dedicated climate control unit  220  that regulates climate properties, such as temperature, humidity, and/or airflow. Many such servers  104  may be configured and/or adapted to utilize at least a portion of the techniques presented herein. 
     1.3. Client Device Configuration 
       FIG. 3  presents a schematic architecture diagram  300  of a client device  110  whereupon at least a portion of the techniques presented herein may be implemented. Such a client device  110  may vary widely in configuration or capabilities, in order to provide a variety of functionality to a user such as the user  112 . The client device  110  may be provided in a variety of form factors, such as a desktop or tower workstation; an “all-in-one” device integrated with a display  308 ; a laptop, tablet, convertible tablet, or palmtop device; a wearable device mountable in a headset, eyeglass, earpiece, and/or wristwatch, and/or integrated with an article of clothing; and/or a component of a piece of furniture, such as a tabletop, and/or of another device, such as a vehicle or residence. The client device  110  may serve the user in a variety of roles, such as a workstation, kiosk, media player, gaming device, and/or appliance. 
     The client device  110  may comprise one or more processors  310  that process instructions. The one or more processors  310  may optionally include a plurality of cores; one or more coprocessors, such as a mathematics coprocessor or an integrated graphical processing unit (GPU); and/or one or more layers of local cache memory. The client device  110  may comprise memory  301  storing various forms of applications, such as an operating system  303 ; one or more user applications  302 , such as document applications, media applications, file and/or data access applications, communication applications such as web browsers and/or email clients, utilities, and/or games; and/or drivers for various peripherals. The client device  110  may comprise a variety of peripheral components, such as a wired and/or wireless network adapter  306  connectable to a local area network and/or wide area network; one or more output components, such as a display  308  coupled with a display adapter (optionally including a graphical processing unit (GPU)), a sound adapter coupled with a speaker, and/or a printer; input devices for receiving input from the user, such as a keyboard  311 , a mouse, a microphone, a camera, and/or a touch-sensitive component of the display  308 ; and/or environmental sensors, such as a global positioning system (GPS) receiver  319  that detects the location, velocity, and/or acceleration of the client device  110 , a compass, accelerometer, and/or gyroscope that detects a physical orientation of the client device  110 . Other components that may optionally be included with the client device  110  (though not shown in the schematic architecture diagram  300  of  FIG. 3 ) include one or more storage components, such as a hard disk drive, a solid-state storage device (SSD), a flash memory device, and/or a magnetic and/or optical disk reader; and/or a flash memory device that may store a basic input/output system (BIOS) routine that facilitates booting the client device  110  to a state of readiness; and a climate control unit that regulates climate properties, such as temperature, humidity, and airflow. 
     The client device  110  may comprise a mainboard featuring one or more communication buses  312  that interconnect the processor  310 , the memory  301 , and various peripherals, using a variety of bus technologies, such as a variant of a serial or parallel AT Attachment (ATA) bus protocol; the Uniform Serial Bus (USB) protocol; and/or the Small Computer System Interface (SCI) bus protocol. The client device  110  may comprise a dedicated and/or shared power supply  318  that supplies and/or regulates power for other components, and/or a battery  304  that stores power for use while the client device  110  is not connected to a power source via the power supply  318 . The client device  110  may provide power to and/or receive power from other client devices. 
     In some scenarios, as a user  112  interacts with a software application on a client device  110  (e.g., an instant messenger and/or electronic mail application), descriptive content in the form of signals or stored physical states within memory (e.g., an email address, instant messenger identifier, phone number, postal address, message content, date, and/or time) may be identified. Descriptive content may be stored, typically along with contextual content. For example, the source of a phone number (e.g., a communication received from another user via an instant messenger application) may be stored as contextual content associated with the phone number. Contextual content, therefore, may identify circumstances surrounding receipt of a phone number (e.g., the date or time that the phone number was received), and may be associated with descriptive content. Contextual content, may, for example, be used to subsequently search for associated descriptive content. For example, a search for phone numbers received from specific individuals, received via an instant messenger application or at a given date or time, may be initiated. The client device  110  may include one or more servers that may locally serve the client device  110  and/or other client devices of the user  112  and/or other individuals. For example, a locally installed webserver may provide web content in response to locally submitted web requests. Many such client devices  110  may be configured and/or adapted to utilize at least a portion of the techniques presented herein. 
     2. Presented Techniques 
     One or more computing devices and/or techniques for hosting virtual chat rooms for a chat room are provided. A user may access a video through a video interface. A chat room may be provided to the user through a chat room interface for discussing the video with other users watching the video. Unfortunately, as the number of users watching the video grow, the chat room may become overwhelming due to the number of users posting messages through the chat room. For example, messages may scroll so fast that the user is unable to read or follow messages of a conversation. Thus, the user may be unable to engage in meaningful conversation because messages of the user may scroll too fast for other users to view. The chat room may lag from the amount of resources (e.g., network bandwidth and computing resources of a client device, a server hosting the chat room, etc.) necessary to receive, process, send, and/or display messages through chat room interfaces (e.g., a client device may be unable to receive hundreds of messages every few seconds over a network and update the chat room interface without lag). Thus, users of the chat room may be unable to have meaningful interaction. Accordingly, as provided herein, the chat room may be sharded into a set of virtual chat rooms (e.g., 50,000 users of the chat room may be split into virtual chat rooms of 100 users each) so that the users may have more meaningful interactions without undue lag from inadequate resources otherwise needed to process a burdensome amount of messages through chat room interfaces (e.g., bandwidth, memory, and/or other computing resources of a client device may be unable to adequately process and display messages of the 50,000 users through a chat room interface without significant lag or other issues). 
     In an example, a chat room may correspond to an overall grouping of users for which messaging functionality is to be provided through chat room interfaces associated with a particular video being accessed by such users. Thus, messages generated by such users may be processed by data structures and/or chat room functionality of the chat room. Instead of displaying all messages generated by the users of the chat room through the chat room interfaces, the chat room is sharded into virtual chat rooms (e.g., a grouping of users assigned to a virtual chat room) so that merely messages of users assigned to a particular virtual chat room are displayed through chat room interfaces accessed by those assigned users. Thus, the virtual chat room corresponds to a subset grouping of users where messages generated by users of the chat room that are not assigned to the virtual chat room are filtered out so that only messages generated by users assigned to the virtual chat room are displayed through chat room interfaces accessed by those assigned users. 
     An embodiment of hosting virtual chat rooms for a chat room is illustrated by an example method  400  of  FIG. 4 . At  402 , users accessing video interfaces, hosting a video, and chat room interfaces associated with a chat room for the video may be identified. For example, a user may access a website hosting a video interface through which a live concert video is being streamed. The website may host a chat interface through which the user may communicate with other users watching the concert. At  404 , signals, associated with the users, may be evaluated to identify user properties of the users. The signals may comprise social network data of the user (e.g., posts by the user, interests of the user, contacts of the user, etc.), a user account of the user (e.g., an age, a place of residence, etc.), locational information from a client device of the user, previous user interactions with chat rooms or other content (e.g., websites visited by the user, content shared by the user through a social network, etc.), etc. Various techniques, such as image recognition, text recognition, feature extract, and/or other signal or content processing techniques may be used to identify user properties from the signals (e.g., image recognition may evaluate a photo shared by the user through a social network to identify an activity being performed by the user such as playing soccer for identifying a soccer interest user property). The user may take affirmative action, such as providing opt-in consent, to allow access to and/or use of signals (e.g., a web browsing history, a user calendar, device sensor information such as camera data or global positioning system (GPS) data, a contact list, a user account profile, etc.), such as for the purpose of identifying user properties used to assign the user to virtual chat rooms (e.g., where the user responds to a prompt regarding the collection and/or use of such information). The user may also opt-out from providing access to such information and/or data or portions thereof (e.g., access may be provided to a user account maintained with a service that hosts the website, but not to a calendar of the user). 
     A user property may be indicative of the user being an active participant (e.g., the user generates a threshold number of messages within a timespan, such as averaging 0.4 or more messages per minute), the user being a passive participant (e.g., the user generates less than the threshold number of messages within the timespan), a user interest (e.g., a user social network post indicates that the user is an advocate of animal rights), a user age (e.g., the user is a teenager), a user location (e.g., locational information of a mobile device carried by the user may indicate that the user is located in a particular part of a city), a user chat room topic preference (e.g., the user frequently participates in animal topic chat rooms), user contacts (e.g., contacts and friends of the user within a contacts list), user responses to keywords (e.g., the user responds with certain words indicative of anger when reading messages with certain keywords such as “hunting” or “ivory”), the user&#39;s usages of keywords (e.g., the user frequently writes messages with the term “funding”), user engagement with one or more additional chat rooms (e.g., the user is routinely a passive participant in videogame chat rooms), user engagement with one or more additional videos, and/or other information indicative of how the user is likely to interact within chat rooms with certain topics and/or other users. 
     At  406 , the chat room may be sharded (e.g., partitioned) into a set of virtual chat rooms. In an example, the chat room may be sharded based upon a virtual chat room occupancy metric. For example, if the virtual chat room occupancy metric specifies a maximum number of users for a virtual chat rooms as 100 or any other number, then the chat room may be sharded into virtual chat rooms with no more than 100 users (e.g., if there are 50,000 users accessing the video, then the chat room may be sharded into 5,000 virtual chat rooms). In an example, the chat room may be sharded and/or users may be assigned to virtual chat rooms based upon a percentage of active participants and a percentage of passive participants (e.g., a virtual chat room may be defined to have a composition of 14% or any other percentage of active participants and 86% or any other percentage of passive participants so that the virtual chat room is not overwhelmed by messages from too many active participants or is too quiet or uninteresting due to too many passive participants). 
     At  408 , the users may be assigned to virtual chat rooms based upon the user properties. In an example, users may be assigned based upon user properties indicative of whether such users are passive participants or active participants so that a virtual chat room has a desired composition of passive participants and active participants. In another example, a first user and a second user may be assigned to the virtual chat room based upon the first user and the second user having previously interacted (e.g., the first user and the second user attended the same school, are contacts of one another, are social network friends, have messaged one another within a chat room, etc.). In another example, a first user and a second user may be assigned to the virtual chat room based upon the first user and the second user sharing a user interest (e.g., a first user property of the first user and a second user property of the second user may indicate that both users have an interest in discussing how to best protect endangered wildlife). It may be appreciated that users may be assigned to the same or different virtual chat rooms based upon various properties, such as two users living within a threshold distance of one another or users being within an age range threshold of one another. 
     At  410 , responsive to a user being assigned to a virtual chat room, the user may be provided with access to the virtual chat room through a chat room interface accessed by the user. In an example, the chat room interface may be populated with chat room information corresponding to the chat room (e.g., the chat room interface may display a total number of users assigned to all the virtual chat rooms, such as the 50,000 users, as opposed to just statistics of the virtual chat room), which may give the user the appearance as though the user is interacting with more than just the users assigned to same virtual chat room as the user. Messages of the chat room (e.g., messages of the 50,000 users) may be filtered for display through the chat room interface based upon messages of users that are assigned to the virtual chat room (e.g., the user may merely see messages from the other 99 users assigned to the same virtual chat room). 
     Users may be reassigned between virtual chat rooms for various reasons. In an example, activity within the virtual chat room may be monitored. A second user may be reassigned from a second virtual chat room to the virtual chat room based upon the activity. For example, the activity may be indicative of user message activity, of users assigned to the virtual chat room, being below a threshold, and thus the second user (e.g., an active participant that creates a threshold number of messages within a certain timespan) may be assigned to the virtual chat room to increase user message activity. Similarly, if too much user message activity is occurring within the virtual chat room which may be overwhelming for users, then an active participant of the virtual chat room may be reassigned to a different virtual chat room. User message activity may be determined based upon a length and/or number of messages being posted to the virtual chat room. 
     In another example, user activity of the user within the virtual chat room may be monitored (e.g., keywords used by the user, reactions by other users to messages posted by the user, a length and/or number of messages posted by the user, whether the user is scrolling back through messages to read them or is not interacting with the chat room interface such as where a different user interface is active, etc.). The user may be reassigned from the virtual chat room to a second virtual chat room based upon the user activity. For example, the user may be reassigned based upon the user activity being indicative of a deviation in user behavior from a predicted user behavior (e.g., the user may have been initially identified as being an active participant but may actually be a passive participant that has not posted a message within 10 minutes). In an example, the user may be reassigned based upon the user activity being indicative of the user generating messages identified as having a negative social dynamic impact upon the virtual chat room (e.g., the user is using certain keywords, profanity, or other message content that may illicit negative responses from other users or may offend other users). In another example, users may be reassigned from the virtual chat room to a second virtual chat room based upon an occupancy of the second virtual chat room falling below an occupancy threshold. 
     In an example, a new user accessing a video interface hosting the video may be identified. Signals of the new users may be evaluated to identify user properties of the new user. The new user may be assigned to the virtual chat room based upon the user properties of the new user (e.g., the new user may be assigned to the virtual chat room based upon the new user having previously interacted with other users assigned to the virtual chat room) and the virtual chat room having an occupancy not exceeding an occupancy threshold. 
     In an example, a new user accessing a video interface hosting the video may be identified. The new user may be assigned to a testing virtual chat room (e.g., because little to no signals of the new users are available to identify user properties of the new user). User activity of the new user within the testing virtual chat room may be monitored to identify a user property of the new user (e.g., the new user may be an active participant that uses complete sentences and proper grammar). The new user may be assigned to the virtual chat room based upon the user property (e.g., the new user may be added as another active participant for the virtual chat room in order to achieve a desired percentage composition of active participants for the virtual chat room; other users within the virtual chat room may use complete sentences and proper grammar, which may be desired by the new user; etc.) 
     In an example, user activity of the user within the virtual chat room may be monitored to create a user chat room activity signal. The user chat room activity signal may be stored for subsequent evaluation for identifying user properties of the user. Responsive to the user accessing a second virtual interface, hosting a second video, and a second chat room interface associated with a second chat room for the second video, the user may be assigned to a second virtual chat room for the second chat room based upon the user chat room activity signal. 
       FIGS. 5A-5F  illustrate examples of a system  500  for hosting virtual chat rooms for a chat room.  FIG. 5A  illustrates a chat room provider  501  that may be configured to provide users with access to a chat room  502  through which the users may discuss a video. For example, a first user may use a first client device  512  to access an e-sports video (e.g., users playing a competitive videogame) through a first video interface  514  (e.g., of an e-sports webpage). A first chat room interface  516  may be provided for the e-sports video (e.g., also displayed within the webpage). In this way, a plurality of users may access video interfaces, hosting the e-sports video, and chat room interfaces associated with a chat room for the e-sports video, such as an nth user using an nth client device  518  to access the e-sports video through an nth video interface  520  and an nth chat room interface  522  for the e-sports video. 
     The chat room provider  501  may identify the users accessing the video interfaces and the chat interfaces (e.g., users accessing the sports webpage). The chat room provider  501  may evaluate signals  506  (e.g., social network data, user account profiles, previous chat rooms accessed by users, previous videos or other content consumed by users, messages written by users, user interests, user ages, user locations, etc.) of the users to identify user properties  508  of the users (e.g., a user may be an active chat room participant that is an avid race car videogame gamer located within San Francisco). 
     The chat room  502  may be sharded into a set of virtual chat rooms  504  (e.g., the chat room  502  of 3,000 users may be sharded into 300 virtual chat rooms with 100 users per virtual chat room). The users may be assigned  510  to virtual chat rooms based upon the user properties  508 . For example, the first user may be assigned to a first virtual chat room. The first user may be provided with access to the first virtual chat room through the first chat room interface  516  (e.g., messages of the 3,000 users may be filtered such that the first chat room interface  516  merely displays messages of other users assigned to the first virtual chat room). The nth user may be assigned to a second virtual chat room. The second user may be provided with access to the second virtual chat room through the nth chat room interface  222  (e.g., messages of the 3,000 users may be filtered such that the nth chat room interface  222  merely displays messages of other users assigned to the second virtual chat room). 
       FIG. 5B  illustrates user activity  530  of the first user within the first virtual chat room being monitored. For example, the first user may have been assigned to the first virtual chat room as an active participant. However, the user activity  530  may indicate that the first user is not interacting with the other users of the first virtual chat room. Accordingly, the first user may be re-categorized as a passive participant, and reassigned  532  from the first virtual chat room to a third virtual chat room that would provide improved chat room user experience having another passive participant (e.g., the first chat room interface  516  may be updated to display messages of the third virtual chat room, resulting in an updated first chat room interface  534 ). 
       FIG. 5C  illustrates the nth user being reassigned  540  from the second virtual chat room to a fifth virtual chat room based upon a friend of the nth user recently joining the fifth virtual chat room. The nth chat room interface  522  may be updated to display messages of the fifth virtual chat room, resulting in an updated nth chat room interface  542 . In this way, users may be dynamically reassigned between virtual chat rooms based upon up-to-date virtual chat room information (e.g., a number of active participants, a number of passive participants, a current total number of assigned users, a number of messages being posted to a virtual chat room, content of messages being posted to the virtual chat room, etc.). 
       FIG. 5D  illustrates a new user using a new client device  550  to access the e-sports video through a new first video interface  552 . The new user may be assigned to a testing virtual chat room within which users are monitored to identify user properties of such user, such as the use of proper grammar, use of explicit language, use of long or short sentences, a number of messages per minute generated, user interests or demographic information described by the user through messages, etc. The new user may be provided with access to the testing virtual chat room through a testing chat room interface  554 .  FIG. 5E  illustrates new user activity of the new user being monitored  560  to identify a user property of the new user. For example, the new user may be a very active participant (e.g., the new user created 2 messages per minute) that is a self-proclaimed gaming expert (e.g., features of a message generated by the user may indicate that the user describes herself as a gaming expert).  FIG. 5F  illustrates the new user being assigned  570  to a sixth virtual chat room based upon the sixth virtual chat room having one or more other users that are gaming experts and the sixth virtual chat room having less than a desired amount of active participants. The testing chat room interface  554  may be updated to display messages of the sixth virtual chat room, resulting in an updated chat room interface  572 . 
       FIG. 6  is an illustration of a scenario  600  involving an example non-transitory machine readable medium  602 . The non-transitory machine readable medium  602  may comprise processor-executable instructions  612  that when executed by a processor  616  cause performance (e.g., by the processor  616 ) of at least some of the provisions herein. The non-transitory machine readable medium  602  may comprise a memory semiconductor (e.g., a semiconductor utilizing static random access memory (SRAM), dynamic random access memory (DRAM), and/or synchronous dynamic random access memory (SDRAM) technologies), a platter of a hard disk drive, a flash memory device, or a magnetic or optical disc (such as a compact disk (CD), a digital versatile disk (DVD), or floppy disk). The example non-transitory machine readable medium  602  stores computer-readable data  604  that, when subjected to reading  606  by a reader  610  of a device  608  (e.g., a read head of a hard disk drive, or a read operation invoked on a solid-state storage device), express the processor-executable instructions  612 . In some embodiments, the processor-executable instructions  612 , when executed cause performance of operations, such as at least some of the example method  400  of  FIG. 4 , for example. In some embodiments, the processor-executable instructions  612  are configured to cause implementation of a system, such as at least some of the example system  500  of  FIGS. 5A-5F , for example.
