Twitter and UChat
I'm still not too sure about the benefits of Twitter. I spent some time perusing the messages and most seem either opinionated or bland. I do think that UChat has some merits and I was really impressed that you could use a virtual white board with your discussions with colleagues. How amazing!
I think I need to spend more time researching both of these options to find more uses but I'm impressed how both of these technologies link communities and ideas.
