Twitter?

I just joined http://www.twitter.com/. On this website you update what you are doing. People can comment on it and or follow you. You can pick who you follow. For example I am currently following Martha Stewart (of course). For example I updated that I am updating my blog. People can comment on that or can choose to follow me. I think that you should sign up for twitter at http://www.twitter.com/. Or I guess you could discuss something and people that agree with you could tell you what they think. The best part is that it is free.
