Twitter has grown up extremely fast. The company announced that they just hit the 200 million mark of monthly active users, which doubles where they were just last last September. Even with the very large number, Twitter is slightly behind the 1 billion monthly active users which Facebook boasts. That doesn’t mean we still aren’t proud!
There are now more than 200M monthly active @twitter users. You are the pulse of the planet. We’re grateful for your ongoing support!
