It's important for us to invest very heavily in protecting user privacy and, to some of the other questions that have been asked today, to take steps to ensure integrity on the platform. I'd say two things about that. The first is that you're right that we need a focus, and particularly across the company what we've tried to do is to get people who work on our products and services—not in the context of the Facebook platform, which we're talking about today, but in other areas as well—to focus their work on promoting integrity, protecting people's data, protecting people's experiences, and promoting our broader obligation. Certainly we need to focus in that way.
As a part of our broader obligation, looking across Facebook developers and other third parties that we have relationships with, in the category of Mr. Kogan for example, we're going to have to invest very heavily in additional personnel and processes to make sure we have oversight in those areas as well.
