What is it? [from the FAQ]
Twitter is a community of friends and strangers from around the world sending updates about moments in their lives. Friends near or far can use Twitter to remain somewhat close while far away. Curious people can make friends. Bloggers can use it as a mini-blogging tool. Developers can use the API to make Twitter tools of their own. Possibilities are endless!
