What is Web 3.0?

There is one feature that everyone wants on their computers: the Do-What-I-Mean button. Imagine that, a computer that understands what you're trying to do and will just up and do it for you. "Make this report look pretty", "take the photos from this camera and put a sideshow on a DVD with my favorite music". Sounds nice ? Unfortunately, something like this is sadly missing from product roadmaps from Apple and Microsoft. The good news is, this is the sort of thing that has been talked about for the World Wide Web for years. And it's getting closer.
