Tim Berners-Lee, director of the World Wide Web Consortium talks in this podcast interview also about Web 2.0:
"Web 1.0 was all about connecting people. It was an interactive space, and I think Web 2.0is of course a piece of jargon, nobody even knows what it means. If Web 2.0 for you is blogs and wikis, then that is people to people. But that was what the Web was supposed to be all along."The transcript of the podcast interview can be found here.
