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.

This is our commitment to users and the people who use our service, is that Facebook's a free service. It's free now. It will always be free. We make money through having advertisements and things like that.

Facebook is inherently viral.

Find that thing you are super passionate about. A lot of founding principles of Facebook are that if people have access to more information and are more connected, it will make the world better; people will have more understanding, more empathy. That’s the guiding principle for me. On hard days, I really just step back, and that’s the thing that keeps me going.

Our mission is to make the world more open and connected. We do this by giving people the power to share whatever they want and be connected to whoever they want, no matter where they are.

Move fast and break things. Unless you are breaking stuff, you are not moving fast enough.

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.
