 It's my first time at GSR, I have done other ITU events, but it's the first time I've gathered with so many regulators all in one place and it's been fascinating to hear the kind of things that regulators are interested in and also what they're concerned about. We all rely on regulators to make good decisions and I think history shows good decisions are ones that come through really thinking this through, learning from other people's experience and you certainly get a feel from this environment that people are here to catch up with each other and also find out how did you handle that issue, because the kind of issues we're dealing with now are pretty common across the world. I took part in a panel on consumer protection, there are a couple of us from industry, there's a consumer representative and then two people who were, about three people who were regulators. What I was conveying is the sense that as Facebook there are certain things that are regulated in terms of how we handle people's data, there are certain aspects of what content is allowed on Facebook that's regulated, but much of what happens on Facebook is not regulated, but nonetheless we take our protection responsibilities and our responsibility for people's safety very seriously and really conveying that you don't have to regulate in order to get good outcomes. We worry that regulation can, if it's based on current technology and how people are using technology now, will get stuck in ASPIC and what we really need is an environment in which all different parties interested in, in technology and its use and development actually are in dialogue together. We think dialogue is often more effective than regulation in a developing and innovative environment. Our vision for the future is for Facebook to achieve its mission which is to connect the whole world. We're about 15% done and we've got 1.3 billion people using Facebook, but that's quite a lot more people who are on the internet who aren't using Facebook yet, but of course even more important are the three and a half billion people who don't have access to the internet. So that's our vision is to try and really close that gap over the next decade.
