Twitter appoints Jack Dorsey as permanent CEO, Dick Costolo resigns from board

It’s official: Jack Dorsey is Twitter’s new CEO.

Costolo announced that he’s resigning from the board. He called Dorsey a “calm and thoughtful leader” and blasted the months of rumors circulating about the company, tweeting:

Twitter’s stock is up 2 percent in pre-market trading.
