Dave Winer: What is Web 3.0?:
...There's always been too much made of death in the tech world, in fact newspapers are still published, you can pick one up at any airport or train station. Many people have them delivered at home. We often go to newspaper websites for the news. Sure, there are problems, and the world is changing, but imho, we'll all do better if something called the San Francisco Chronicle continues to be published, even though the form of the newspaper will certainly change in the future. It would be a waste of a tradition, of a good coral reef, if newspapers really died. They need to change, and imho, when that change happens, we will safely be in the era of Web 3.0.
Sramana Mitra has developed a compelling definition of Web 3.0, and differs on the viewpoint that Semantic Web would be the essence of the next generation of the Internet. Please read this: Web 3.0 = (4C + P + VS).
I actually believe terms like "Web 2.0" and "Web 3.0" obscure more than they inform. I posted this because of the evolution of Dave Winer's thought in regards to newspapers.
