The Australianreports that Twitter has reached its 15 billionth tweet just three months after hitting its 10 billionth. Twitter also revealed that 300,000 new accounts are being added daily on Twitter.
For the first time since the site launched in March 2006, Twitter released its numbers, with 105 million registered users and 300,000 new accounts being added on average each day.
The Australian also calls Twitter an "online blog site," which sounds a little redundant to us.
