Tim O'Reilly attempts to clarify just what is meant by Web 2.0, the term first coined at a conference brainstorming session between O'Reilly Media and MediaLive International, which also spawned the Web 2.0 Conference.

Furthermore, this great article called All We Got Was Web 1.0, When Tim Berners-Lee Actually Gave Us Web 2.0 by Dion Hinchcliffe explains the Web 2.0 phenomena as much more about a change in people and society than technology. As an intersection of participation, penetration and adoption.
