It's not clear what the reforms entail, although Williams hints that Twitter might not be waiting for a new permanent CEO to shift direction. Either way, it's easy to see why the company would have a change of heart. While Twitter is still adding lots of users, it's also losing money. Critics regularly accuse it of having a lack of focus (Williams now wants it to be a "real-time news platform") and doing little to innovate besides snapping up other companies. Stronger third-party support might save Twitter from depending so heavily on its own apps and websites -- it could ride the success of someone else's smash hit by selling ads and generating buzz.
