Description:	Twitter allows users to post text updates via SMS, instant messaging, email, Twitter’s website and third party applications. Users have their own profile page that displays their latest updates. In addition, users can become "friends" with one another, or simply be a "follower." Other than reading another person's profile page, a user can also receive others’ updates through text messages, RSS or third party applications. Twitter itself is a free service, though users may have to pay text messaging charges to the phone carriers.
