Twitter is a free social networking and micro-blogging service that allows users to send updates (otherwise known as tweets) which are text-based posts of up to 140 characters in length. Updates are displayed on the user's profile page and delivered to other users who have signed up to receive them. The sender can restrict delivery to those in his or her circle of friends (delivery to everyone being the default). Users can receive updates via the Twitter website, instant messaging, SMS, RSS, email or through an application such as Twitterrific or Facebook. Twitter does not take advertising, and so does not provide media data. For example, its ‘About Us’ page contains only employees’ Twitter avatar links.
