In what would be the biggest public event (for a consumer-Web company) since Facebook, everyone’s asking when Twitter is planning its IPO. Yet, Ali Rowghani, the microblogging leader’s

publicly traded company.” But, Twitter CEO Costolo isn’t worried. “He’s a calm and strategic thinker,” Costolo says of Rowghani.
