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.

In terms of doing work and in terms of learning and evolving as a person, you just grow more when you get more people's perspectives... I really try and live the mission of the company and... keep everything else in my life extremely simple.

Helping a billion people connect is amazing, humbling and by far the thing I am most proud of in my life.

You grow more when you get more people's perspective.

It's tough to say, exactly, what things will look like in three to five years, but there's a lot of work to do in just moving along the path that we've already set out.

The primary things that people do on the Facebook is they use it to share with their friends and the people around them and their community, and they use it to keep in touch with people.

I actually remember very specifically the night that I launched Facebook at Harvard. I used to go out to get pizza with a friend who I did all my computer science homework with. And I remember talking to him and saying I am so happy we have this at Harvard because now our community can be connected but one day someone is going to build this for the world.
