Another Web 2.0 Explanation

A friend of mine just sent over this video explanation of the Web 2.0 internet phenomenon.  It's been circulating like crazy and may be old news to many of you but I found it interesting and entertaining.  It reminds me of a similar video called Epic that I first saw in January 2005 at the NewCommForum conference (by the way, the next NewCommForum event is next month in Vegas. There is a great line up of speakers and if you can, I strongly suggest you find a way to get there).
