What Comes After Web 2.0?

A prescient question posted by one of my colleagues this morning.

My answer, of course, was Web 3.0!

From whatis.com:

The idea of the Semantic Web was created by World Wide Web inventor Tim Berners-Lee. Berners-Lee’s concept is that the web as a whole can be made more intelligent and perhaps even intuitive about how to serve a user’s needs. Although search engines index much of the web’s content, they have little ability to select the pages that a user really wants or needs. Berners-Lee foresees a number of ways in which developers and authors, singly or in collaboration, can use self-descriptions and other techniques so that context-sensitive programs can intuit what users want.

From Wikipedia:

Web 3.0, a phrase coined by John Markoff of the New York Times in 2006, refers to a supposed third generation of Internet-based services that collectively comprise what might be called ‘the intelligent Web’—such as those using semantic web, microformats, natural language search, data-mining, machine learning, recommendation agents, and artificial intelligence technologies—which emphasize machine-facilitated understanding of information in order to provide a more productive and intuitive user experience.

From my colleague:

I ran across something interesting this afternoon that might be heading in that direction. Actually, it’s not all that different from 2.0 because it still builds on information sharing and collaboration – but it is cool and it is down the road.

So what do you think? What comes next?
