I found this interview with Tim O’Reilly on collective intelligence and Web 2.0 rather fascinating. (Does that make me a total geek?) Some tidbits:
Google’s realization that links were a kind of user generated “voting” on the best site for a topic (i.e. Page Rank) and could be used to deliver better search results was arguably the real beginning of the Web 2.0 revolution.
Web 2.0 is held to an unrealistically high standard. Instead, people have to view Web 2.0 and collective intelligence in its proper context. These aren’t magic bullets that solve every problem, and collective intelligence has its downside – collective stupidity, collective cupidity, and the like.
