Tweet on Twitter

So Twitter is finally taking off and folks are finally catching wind of what this social networking tool can do. I'm not 100% sure if I'm a big fan, but I can appreciate the concept. In a nutshell, Twitter allows you to update your "social" status via text messaging on your mobile phone. If you have an iPhone it's even more powerful, allowing you to use GPS capabilities to allow your network to know where you are at any given time (pretty scary). I do like the fact that you can limit who has access to your status and that you can a set up individual groups to give certain access rights to your status. So who else is using Twitter besides me?
