Explore Twitter on Experts Exchange

Twitter is an online social networking service that enables users to send and read short 140-character messages called "tweets". Users can group posts together by topic or type by use of hashtags – words or phrases prefixed with a "#" sign. Similarly, the "@" sign followed by a username is used for mentioning or replying to other users. Users access Twitter through the website interface, SMS, or mobile device app. The Twitter Web interface uses the Ruby on Rails framework. The service's application programming interface (API) allows other web services and applications to integrate with Twitter.
