TWITTER .

_{We all know Twitter is the new MySpace. Here, you can update everyone on the latest things you've been up to, wether it's hanging out with your BFF Jill or helping to organize Paris Fashion Week. You can also follow your friends and see what they've been up to and comment on their entries, so it's a whole new way of socializing when you're just too lazy to step outside. Basically, everyone gathering together to answer the age-old question: "What are you doing?"}
