Beautiful Defination of Web 2.0
Web 2.0 encapsulates the idea of the interactivity of web-delivered content. I think Web 2.0 as the way that business embraces the strengths of the web and uses it as a platform. We considers that Eric Schmidt's abridged slogan, don't fight the Internet, encompasses the essence of Web 2.0 — building applications and services around the unique features of the Internet.Web 2.0 websites allow users to do more than just retrieve information.

These sites may have an "Architecture of participation" that encourages users to add value to the application as they use it.
