Twitter hasn’t exited yet, and there are still concerns about whether it’ll truly grow into its nosebleed valuation. Still, I think it’s safe to say that any question about Costolo’s CEO chops seems to be unequivocally answered by now. In recent weeks, I’ve heard several investors say he’s saved the company. Since he joined, Twitter has focused on revenue and seems to at least sport good performance metrics even if it can’t share absolute numbers. At the D11 conference today, Costolo cited a Bonobos campaign that was 13 times more effective than campaigns run elsewhere. He’s cited similar numbers elsewhere.

So perhaps Costolo betrayed his secret today at D when he repeatedly answered questions about how Twitter would innovate and expand and develop its product by saying, frankly, it wouldn’t. “We look at what can we remove,” he said, adding later. “We’re not trying to add new things into Twitter. My challenge is how do you pull things out of it?”

My Two Cents

Addition by subtraction equals Twitter success. But that's really not true. What really seems to be true about Twitter is that they want to keep that same small footprint. Twitter is almost like a neutron star: so small and dense that it can fill you up to the brim with really small bites: lots of them! The genius of Twitter is so many small bites, over and over and over. Facebook can't touch that.
