A free social messaging tool that lets people stay connected through brief text
message updates up to 140 characters in length. Twitter is based on you
answering the question "What are you doing?" You then post thoughts,
observations, and goings-on during the day. Your update is posted on your
Twitter profile page through
SMS text messaging, the
Twitter Web site, instant messaging, RSS, e-mail, or through other social
applications and sites, such as
Facebook.
