Web 2.0 - Next big thing for the classroom?

So, in class we are talking about Web 2.0. I thought I would post this video from the guy at TechCrunch. This more or less gives a definition of what Web 2.0 from more of a business stand point. The question arises about is this a "bubble" or is this here to stay? So, then that leads me to the next question...How is this going to impact education and the learning environment and how is this going to effect teaching?

One piece that worries me a bit is all of the "movable" content. Are the student's thoughts going to be individual or just a compilation of other people's web content that is pieced together and looks nice. At what point does the technology start to have too much of an influence on how people have thoughts.
