I suspect the challenges in running a scalable distributed realtime system like Twitter are fairly significant. And while I don't know how much of Twitter's operating expenses are attributable to the efficiency of that platform, if the new CEO wants to keep expenses lower than revenue, they would potentially be very concerned about how to make that platform efficient, which probably has some really interesting systems engineering challenges.
