A rumor about Twitter 's top executive reshuffle at AllThingsD  was quickly confirmed by Twitter CEO Dick Costolo himself . Ali Rowghani is moving from chief financial officer to chief operating officer, while Mike Gupta becomes the new CFO.
Rowghani was previously CFO at Pixar . Gupta, meanwhile, recently left Zynga for Twitter. Zynga's business chops, it could be argued, are a little less certain  than Pixar's. In fact, brand new analysis  by metrics firm AppStats suggests that throughout 2012 Zynga bled some 19 million daily active users overall--even as its new FarmVille 2 game gained 8.4 million new daily active users. DAUs are to Zynga as the Monthly Active User tally is to Facebook: A simple measure of how many customers are actively engaged in its systems, and thus an indicator of how much revenue the company can command.
Is this executive change a sign of confidence for Twitter's year ahead? Or does it suggest managerial uncertainty at the social network?
