My class spent about an hour today thinking and talking about Web 2.0. What struck me about our conversation was how much the class already knew about Web 2.0–and how mainstream most Web 2.0 applications have become. The social media, in other words, have become almost transparent. We use them so much, we don’t really even realize they are there.

What’s still on the horizon, of course, is the idea of Web 3.0, the so-called semantic (knowledge) web. The main idea of this new and largely theoretical version of the web is that computers will learn our language, so that will be able to communicate with them as well as we communicate with human beings. This video created by Kate Ray, a Journalism/Psychology major at NYU, does a great job of explaining the idea:
