Web 2.0... More Useful Everday

Just have to share that I have been "tweeting" and following several tweets here at CoSN.  It is interesting to communicate and collaborate real-time during a keynote.  I found one group on-line that was sharing virtual notes on Google docs.  What a great use of web 2.o.  Imagine how useful this document will be in the end with all of these tweeters notes on it.
