I'm just wondering if any of you here have a Twitter account. What it basically can be described as is a "mini-blog." Each post may only contain up to 140 characters. What's really cool about it though is that you can update it by sending an IM to it, using the web interface, or by sending a text message via phone. It's just fun to post random things while I'm working away on my homework. I've got a link to my account in my signature at the moment. :)
