Twitter CEO Dick Costolo confirmed via tweet today that the massive social network is now being headed by a new chief operating officer and chief financial officer.
It will be interesting to see what these two will do in coming up with ideas to create more revenue for Twitter.
In the past few months, the social network has been pushing hard on structural changes in hopes that it will boost profitability. In September, it announced a new mobile-first strategy aimed at settling on more user experience consistency across its many clients -- Web, iPhone, iPad, and Android -- a move that it clearly hopes will help increase advertising revenue.
