The thing that we are trying to do at Facebook is just help people connect and communicate more efficiently.

I think people tend to be worried about every new technology that comes along.

Right now, with social networks and other tools on the Internet, all of these 500 million people have a way to say what they're thinking and have their voice be heard.

Don't discount yourself, no matter what you're doing.

There's a difference between being obsessed and being motivated.

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.

In the future, I think you are going to want to capture a whole scene, a room, to be able to transport to that. To be able to stream what you are doing live and have people be able to interact in that space.
