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

What really motivates people at Facebook is building stuff that they're proud of.

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.

I do everything on my phone as a lot of people do.

I started the site when I was 19. I didn't know much about business back then.

People at Facebook are fairly used to the press being nice to us or not nice to us.

The companies that work are the ones that people really care about and have a vision for the world so do something you like.

The only meat I eat is from animals I've killed myself.

We're running the company to serve more people.

We want Facebook to be one of the best places people can go to learn how to build stuff. If you want to build a company, nothing better than jumping in and trying to build one. But Facebook is also great for entrepreneurs/hackers. If people want to come for a few years and move on and build something great, that's something we're proud of.

My goal was never to just create a company. A lot of people misinterpret that, as if I don't care about revenue or profit or any of those things. But what not being just a company means to me is not being just that - building something that actually makes a really big change in the world.

There are a few other things that I built when I was at Harvard that were kind of smaller versions of Facebook. One such program was this program called Match. People could enter the different courses that they were taking, and see what other courses would be correlated with the courses they are taking.

When you give everyone a voice and give people power, the system usually ends up in a really good place. So, what we view our role as, is giving people that power.

Advertising works most effectively when it's in line with what people are already trying to do. And people are trying to communicate in a certain way on Facebook - they share information with their friends, they learn about what their friends are doing - so there's really a whole new opportunity for a new type of advertising model within that.

I literally coded Facebook in my dorm room and launched it from my dorm room. I rented a server for $85 a month, and I funded it by putting an ad on the side, and we've funded ever since by putting ads on the side.

People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people - and that social norm is just something that has evolved over time.

Back, you know, a few generations ago, people didn't have a way to share information and express their opinions efficiently to a lot of people. But now they do. 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.

Facebook is inherently viral. There are lots of sites that include a contact importer, and for lots of them it doesn't really make sense. For Facebook it fits so well. It wasn't until a few years in that we started building some tools that made it easier to import friends to the site. That was a huge thing that spiked growth.

Facebook is uniquely positioned to answer questions that people have, like, what sushi restaurants have my friends gone to in New York lately and liked? These are queries you could potentially do with Facebook that you couldn't do with anything else, we just have to do it.

Games is probably the biggest industry today that has gone really social, right. I mean, the incumbent game companies are really being disrupted and are quickly trying to become social. And you have companies like Zynga.
