In February, 2009 Sir Tim Berners-Lee spoke to TED, the Technology, Entertainment, and Design group responsible for inviting experts who, in TED's words, "are challenged to give the talk of their lives (in 18 minutes)". His discussion was not on web 2.0 but beyond, into a subset of the semantic web or web 3.0, that represents a sea change in the way we will obtain and view data on the web.
