Web 2.0 - What does it really mean?

Random video by a professor at Kansas State University.

I thought this video was cool in the way that it would start with one sentence, then chance a few words, or even just a few letters, and completely change the meaning. I also thought it was interesting how the typing came right in the middle of what was already written to explain what he wanted to say about it. I also liked how it named the things we need to rethink by replacing the word with the next one. We all do need to rethink ourselves.
