I still don't understand what Web 2.0 is, but the next version is coming and I fear it. I don't want my MacBook getting inside my head-hell, even I don't want to be in there! "[T]he Web 3.0 browser will act like a personal assistant. As you search the Web, the browser learns what you are interested in. The more you use the Web, the more your browser learns about you and the less specific you'll need to be with your questions. Eventually you might be able to ask your browser open questions like 'where should I go for lunch?' Your browser would consult its records of what you like and dislike, take into account your current location and then suggest a list of restaurants."
"Some Internet experts believe the next generation of the Web — Web 3.0 — will make tasks like your search for movies and food faster and easier. Instead of multiple searches, you might type a complex sentence or two in your Web 3.0 browser, and the Web will do the rest. In our example, you could type "I want to see a funny movie and then eat at a good Mexican restaurant. What are my options?" The Web 3.0 browser will analyze your response, search the Internet for all possible answers, and then organize the results for you." [HowStuffWorks]
