Web 2.0 refers to all the major technologies that allow people to create and share online information. The method is ideal as companies and people do not have to create websites. The main communication methods used include blogs, wikis, tweets and social media. An organization can retrieve a lot of information from these sites. Blog Blog is a personalized online journal designed for people to write about their daily experiences and allow readers to put below their comments. It consists of two main components, the journal and the navigation pane. The American Express can use the blog to store, retrieve or form data. Using my link, the American Express can be able to access the website. It also has “side boxes“, which contain information that the owner would like to display. For storage purposes, there is an archive section, which aids in grouping information as it is received. For security purposes, the company can choose to block anonymous logins by sending its URL to its members only. Moreover, no other member can update the company’s profile apart from it. The information can also be locked to be viewed by authorized people (Anderson, 2007). Wiki Wiki is a server software which enables its users to create or edit a page on any web browser. It allows people to edit as well as update information. Most of the wikis are informative and educate people on a given subject. It enables its user’s develop, plan and work on projects together. For the company storage purposes, information in wikis is stored in a chronological order and may be used to build the company’s knowledge. This makes it easy to retrieve any information more over; the company information is secure since the website can block some information (Anderson, 2007). Tweet Tweet is a service that allows people to communicate using quick and frequent messages, which are usually less than 140 characters. Tweets also have archives where the company can store its information in a chronological order. For security purposes, tweets do not allow html pages to be used. In addition, it is possible to block some of the messages on the tweet site. Through Twitter, the American Express company can regularly receive updates from many sources of information. The organisation will also be able to access a wide range of information through comments and suggestions from different people.

American Express can also use Google+ to get any specialized information contained in blogs, wikis, videos and catalogs.
