A couple weeks ago, I speculated as to whether or not twittering was a sign of a mid-life crisis. Commenter James Barnes pointed out that Twitter users had a higher average age than Facebook and Myspace users: 31, 27, and 26 repectively. But now Twitter has become cool for everyone. So if you're still unsure as to whether or not you want to join twitter, or if you just don't know all that much about twitter, I hope you will find this video instructive.
Feel free to direct your GW peers to your twitter stream :)
