what is it?

When Tim O'Reilly first coined the term Web 2.0 in 2004, his intention was to describe a revolution in the world of Internet, but he found it difficult to define the term precisely.
Web 2.0 refers to a perceived second generation of web-based communities and hosted services such as social-networking and wikis which facilitate interactive information sharing, interoperability, user-centered design and collaboration.
Τhe term Web 2.0 suggests a new version of the World Wide Web.
