What is Web 2.0 Anyway?

Web 2.0 refers to web-based communities in which collaboration is facilitated and sharing between users occurs. This takes place with wikis, blogs, social bookmarking, and similar online resources. The concept of Web 2.0 began with a 2004 conference brainstorming session between publisher Tim O'Reilly and MediaLive International. Some of the buzz words associated with Web 2.0 are "social networking" and "user-driven content." Some websites that have been considered Web 2.0 worthy are Wikipedia, flickr, del.icio.us, Google Docs, and this blog.
