What Are You Doing?

Twitter exists to answer one question - What are you doing?

You setup an account and log in, then describe what you're up to in 140 characters or less. Update your current activities via the website, SMS or instant message. Add your friends and be kept abreast of what they are up to by 'following' them. Their updates can be sent to you via text message, or simply viewed on the home page.

Set your sleep time and you won't be disturbed by updates through the night either. And if you're the forgetful type, set the auto-nudge feature to be reminded by SMS if you haven't updated today.
