The basis of our partnership strategy and our partnership approach: We build the social technology. They provide the music.

I know it sounds corny, but I’d love to improve people’s lives, especially socially… Making the world more open is not an overnight thing. It’s a ten-to-fifteen-year thing.

It used to be the case, like, you'd switch jobs, and then maybe you wouldn't keep in touch with all the people that you knew from that old job. Just because it was too hard. But one of the things that Facebook does is it makes it really easy to just stay in touch with all these people.

Building a mission and building a business go hand in hand.

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

On engagement, we're already seeing that mobile users are more likely to be daily active users than desktop users. They're more likely to use Facebook six or seven days of the week.

I'm trying to make the world a more open place by helping people connect and share.
