Web 2.0 is a piece of jargon

For the inventor of the Web, Sir Tim Berners-Lee, there is a tremendous sense of déjà vu about all this. When asked in an interview for a podcast, published on IBM’s website, whether Web 2.0 was different to what might be called Web 1.0 because the former is all about connecting people, he replied:

"Totally not. Web 1.0 was all about connecting people. It was an interactive space, and I think Web 2.0 is 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. And in fact, you know, this 'Web 2.0', it means using the standards which have been produced by all these people working on Web 1.0."
