definition: Twitter is an application that permits users to post 140-character status updates, or “tweets,” to their Twitter profile in answer to the question, “what's happening?” from the Internet, mobile devices, and third-party Web applications. The model of Twitter users “following” other Twitter users defines friendship ties. [Source: Encyclopedia of Social Networks; Twitter]
