I think Facebook is an online directory for colleges... If I want to get information about you, I just go to TheFacebook, type in your name, and it hopefully pulls up all the information I'd care to know about you.

A lot of times, I run a thought experiment: 'If I were not at Facebook, what would I be doing to make the world more open?'

When we are thinking about stuff like embeds, we are not thinking about how we are competing with YouTube. We are thinking about how are we going to make it more useful for people to share stuff on Facebook.

People like to talk about war.

It wasn't until we got our first office in Palo Alto where things became more like a company. We never went into this wanting to build a company.

We have a rule that if you check in code, you have to maintain it. So I mostly code on the side. I don't check in code anymore.

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

Move fast with stable infrastructure.

I'm trying to make the world a more open place.

The question isn't, 'What do we want to know about people?', It's, 'What do people want to tell about themselves?'

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

I wear the same outfit or, at least, a different copy of it almost every day.

You get a reputation for stability if you are stable for years.

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

I will only hire someone to work directly for me if I would work for that person. It's a pretty good test.

Mobile is a lot closer to TV than it is to desktop.

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

The thing I really care about is the mission, making the world open.

Connectivity is a human right.

Figuring out what the next big trend is tells us what we should focus on.
