Twitter is a social networking and micro-blogging service created in 2006 by Jack Dorsey that allows users to post and read messages called tweets. Tweets are limited to 140 characters, which allows users to share breaking news, local information from friends, deals, or other timely updates. Users can follow others on Twitter, see their latest tweets, and re-tweet messages to their own followers to spread information. Trending topics show what is most frequently being tweeted about at any given moment.
