Twitter is a social networking and micro-blogging service that allows its users to send and read other users’ updates (known as tweets), which are text-based posts of up to 140 characters in length. Estimates of the number of daily users vary as the company does not release the number of active accounts. In November 2008, Jeremiah Owyang of Forrester Research estimated that Twitter had 4-5 million users. A February 2009 Compete.com blog entry ranks Twitter as the third largest social network (behind Facebook and MySpace), and puts the number of users at roughly 6 million and the number of monthly visitors at 55 million.
