I have a Twitter account now. It's at
http://twitter.com/MarkDuval I'm not sure I entirely get the point of it yet considering, as I've mentioned on here before, Facebook does the same thing with its status updates (and then more with the rest of Facebook) and I have a livejournal here which lets me type in posts of more than just 140 characters.
But I'm curious about it, so, there I am.
