Venture Beat reports that during the D9 conference today Twitter's CEO Dick Costolo said, " Costolo was asked directly during the conference if Twitter was in fact generating profits, he dodged the question, saying only, "We don’t need to optimize for near-term revenue. We need to optimize for long-term success."

It continues to add new features as well including today's announcement that it will launch its own internal photo sharing service.
