 * All About Web 2.0**

A [|tag cloud] (a typical Web 2.0 phenomenon in itself) presenting Web 2.0 themes. The term "**Web 2.0**" is commonly associated with web applications that promote interactive information sharing, interoperability, user-centered design, and collaborationon the World Wide Web. Examples of Web 2.0 include web-based communities, hosted services, web applications, social-networking sites, video-sharing sites, wikis, blogs, mashups, and folksonomies. A Web 2.0 site allows its users to interact with other users or to change website content, in contrast to non-interactive websites where users are limited to the passive viewing of information that is provided to them. The term is associated with [|Tim O'Reilly] because of the [|O'Reilly Media] Web 2.0 conference in 2004. Although the term suggests a new version of the [|World Wide Web], it does not refer to an update to any technical specifications, but rather to cumulative changes in the ways [|software developers] and [|end-users] use the Web. Whether Web 2.0 is qualitatively different from prior web technologies has been challenged by World Wide Web inventor [|Tim Berners-Lee], who called the term a "piece of jargon" — precisely because he intended the Web to embody these values in the first place.

**Characteristics**

[|Flickr], a Web 2.0 web site that allows its users to upload and share photos, allows users to do more than just retrieve information. They can build on the interactive facilities of "[|Web 1.0]" to provide "Network as platform" computing, allowing users to run software-applications entirely through a browser. Users can own the data on a Web 2.0 site and exercise control over that data. These sites may have an "Architecture of participation" that encourages users to add value to the application as they use it. The concept of Web-as-participation-platform captures many of these characteristics. Bart Decrem, a founder and former CEO of Flock, calls Web 2.0 the "participatory Web" and regards the Web-as-information-source as Web 1.0. The impossibility of excluding group-members who don’t contribute to the provision of goods from sharing profits gives rise to the possibility that rational members will prefer to withhold their contribution of effort and free-ride on the contribution of others. This requires what is sometimes called [|Radical Trust] by the management of the website. According to Best, the characteristics of Web 2.0 are: rich user experience, user participation, dynamic content, [|metadata], web standards and scalability. More changes are expected to improve the interactiveness of the web , but add-ons such as Flash and Java have made this less necessary.
