Twitter CEO Dick Costolo announced Thursday he's stepping down.
The announcement was made official — where else? — on Twitter. In a document linked in a tweet from the company's account, Costolo said, "I am tremendously proud of the Twitter team and all that the team has accomplished together during my six years with the Company."
He didn't give a reason for his departure.
