Facebook is awesome!

I've just signed up with Facebook, then I addicted to it. It's because I can link to my friends and meet some new friends through the network of my friends. Facebook has been growing exponentially. Previously, it was used exclusively within Harvard University, then spread to other universities and schools, finally opened up to everyone with a valid email address about a year ago. It has over 30 million users, and has been growing at a rate over 500 percent in the last six months. Facebook has started to allow members to trade within the network.
