Today marks the sixth year since founder Jack Dorsey and Twitter’s first members started using the communications platform. And for its birthday, the company has posted a number of stats about its growth in usage. Twitter now has 140 million active users is seeing 340 million Tweets a day (more than double what it was last March). A year ago, Twitter was seeing 140 million Tweets per day.
Last year, Dorsey shared a number of details about how Twitter first emerged. On March 21, 2006, Dorsey sent Twitter’s (then Twttr) famous first (non-automated) tweet: “inviting coworkers”.
2012 has been an important year for Twitter, as the company has expanded its advertising products, and made a number of key acquisitions, including most recently Posterous. And we’re only three months into the year, so we can expect much more from the company in 2012.
