Launching Twitter Account

I joined the twitter legions, yesterday, Sunday, January 9th. The characteristic of brevity is most appealing. It is a reminder to me to get to the point (if I twittered this blog post, I would be way over the character limit). I have chosen to follow the first seven twitter accounts that had anything to do with math as an interest. I am hoping to find some ideas and /or sites that will help me introduce math topics to my students or keep their interest. I am beginning to see where this could be a valuable resource. I am also looking forward to a reply to one of my first three tweets!
