CEO Dick Costolo will resign, to be replaced in the interim by Jack Dorsey.

Casey Newton at The Verge writes that it was not unexpected.

Twitter CEO Dick Costolo is out at Twitter, a source at the company tells The Verge. Costolo told the staff today he would be stepping down in the next few weeks. Twitter co-founder Jack Dorsey will be interim CEO while the board conducts a search for a permanent replacement. Costolo's future at the company had been in question for the past six months as anemic user growth and a struggling stock price have led some investors to call for a change.
