#WhatIsTwitter?

Twitter is a free service that allows users to answer the question “What’s happening?” in 140-character messages known as “tweets.” Users can follow others, enabling their tweets to appear on the user’s homepage as they are published.

While 140 characters might seem brief, Twitter users can share links to longer articles, blogs, videos, etc., for more information. Twitter also allows its users to “retweet” particularly appealing tweets that a different user has authored, while simultaneously providing an acknowledgment to the original author. Twitter allows us to create our own catalog of professional resources, and with more than 500 million users, Twitter is a popular way to connect with others.
