A good explantion of Twitter

twitter.zappos.com: "I know that I've been spending about half an hour every time I try to convince my friends to sign up for Twitter. At first, they think it sounds interesting but aren't really motivated to sign up. Sometimes it's been a multi-week long process. But finally they relent and sign up, probably just so they can shut me up. I walk them through the signup process, step by step, and then slowly but surely, they become addicted and their lives are never the same again.So to save me from having to give the same spiel over and over again, I decided to create this page for anyone new to Twitter."
