The next phase of the world wide web.

“Web 2.0 is a term popularized by O’Reilly Media and MediaLive International as the name for a series of web development conferences that started in October 2004. It has since come to refer to what some people describe as a second phase of architecture and application development for the World Wide Web. Web 2.0 applications often use a combination of techniques devised in the late 1990s, including public web service APIs (dating from 1998), Ajax (1998), and web syndication (1997). They often allow for mass publishing (web-based social software). The term may include blogs and wikis. To some extent Web 2.0 has become a buzzword, incorporating whatever is newly popular on the Web (such as tags and podcasts). A consensus on its exact meaning has not yet been reached.” (From wikipedia)
