In 2008 everything was about Facebook. Here in 2009 it's still about Facebook, but more and more are joining Twitter.
But what is Twitter? Twitter is not new, but has been around for quite a few years. Basically Twitter is a very simple program that "only" has a status message as it's basic. The "thing" is that you can follow your frinds, but also make it update your status on Facebook also.
