Twitter's Seven Year Anniversary Today

Has become quite popular

Seven years ago today the first tweet appeared on a then private social networking website. "Just setting up my twttr," Jack Dorsey, the co-founder of Twitter, tweeted on March 21, 2006. Since that day, or really since Twitter's official public launch on July 15, Twitter has exploded, changing the way we interact with people on the Internet and get short bursts of information.
