I'm not sure I really understand the point to Twitter. I was reading an article on the legitimacy of it today. I don't see why it is any better than Facebook. All you can do on Twitter is comment, whereas, you can do that on Facebook as well as so much more. I have heard the argument that you can't have conversations through your Facebook updates but just today, I had a conversation with a girl on Facebook that I have not spoke to in over a year because I made a comment about the Eagles getting a wide receiver. I have a Twitter, but I am still not sure that I see much purpose for it.
