Pues el Sr. Tim Berners-Lee, creador de la world wide web, opina que "Web 2.0" no es nada:
"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, quote, it means using the standards which have been produced by all these people working on Web 1.0. It means using the document object model, it means for HTML and SVG, and so on. It's using HTTP, so it's building stuff using the Web standards, plus JavaScript, of course. So Web 2.0, for some people, it means moving some of the thinking client side so making it more immediate, but the idea of the Web as interaction between people is really what the Web is. That was what it was designed to be as a collaborative space where people can interact.
Now, I really like the idea of people building things in hypertext, the sort of a common hypertext space to explain what the common understanding is and, thus, capturing all the ideas which led to a given position. I think that's really important. And I think that blogs and wikis are two things which are fun. I think they've taken off partly because they do a lot of the management of the navigation for you and allow you to add content yourself. But I think there will be a whole lot more things like that to come -- different sorts of ways in which people will be able to work together. The semantic wikis are very interesting. These are wikis in which people can add data and then that data can then be surfaced and sliced and diced using all kinds of different semantic Web tools. So that's why it's exciting the way people, things are going, but I think there are lots of new things in that vein that we have yet to invent."
