I really do recommend everybody use Twitter. It is a very simple and easy way to stay in touch and a fun way to let everyone know what you're up to, and quick thoughts, all within 140 characters. Come on, you know you want to. You've heard all about it, all over the TV, radio and internet. Check it out. It's fun. The coolest thing about it is that there a lot of celebrities and companies that have signed up to Twitter that you can follow and communicate with, because there are no restrictions. Of course you can block a few people from following you, if you so choose, but otherwise it's pretty wide open.
I myself had a back and forth communication with David Gregory of NBC's Meet The Press, and I felt giddy! So try it out. It's cool.
