When I was in college, I remember thinking to myself, this internet thing is awesome because you can look up anything you want, you can read news, you can download music, you can watch movies, you can find information on Google, you can get reference material on Wikipedia, except the thing that is most important to humans, which is other people, was not there.

Google, I think, in some ways, is more competitive and certainly is trying to build their own little version of Facebook.

When you give people ability to stay connected with all the people they care about, and you make it so they can express new things about themselves or in communication with other people who they care about, then you just open up new possibilities. You make it so people can stay connected in ways that they couldn't before.

When I'm introspective about the last few years I think the biggest mistake that we made, as a company, is betting too much on HTML5 as opposed to native... because it just wasn't there. And it's not that HTML5 is bad. I'm actually, on long-term, really excited about it. One of the things that's interesting is we actually have more people on a daily basis using mobile Web Facebook than we have using our iOS or Android apps combined. So mobile Web is a big thing for us.

No one has done a study on this, as far as I can tell, but I think Facebook might be the first place where a large number of people have come out. We didn't create that - society was generally ready for that. I think this is just part of the general trend that we talked about, about society being more open, and I think that's good.

We are so fortunate that our work in connecting the world through Facebook has given us the ability to give back to our local community, our country and the world -- and to work to improve education, health care and internet access for everyone, to serve our community in San Francisco, we can think of no better place to focus than The General.

Our goal is not to build a platform; it's to be cross all of them.
