The real question for me is, do people have the tools that they need in order to make those decisions well? And I think that it's actually really important that Facebook continually makes it easier and easier to make those decisions... If people feel like they don't have control over how they're sharing things, then we're failing them.

People influence people. Nothing influences people more than a recommendation from a trusted friend. A trusted referral influences people more than the best broadcast message. A trusted referral is the Holy Grail of advertising.

Virtual Reality is going to be an important technology. I am pretty confident about this.

I think that people just have this core desire to express who they are. And I think that's always existed.

Virtual Reality is really a new communication platform. By feeling truly present, you can share unbounded spaces and experiences with the people in your life. Imagine sharing not just moments with your friends online, but entire experiences and adventures.

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

We've changed our internal motto from "Move fast and break things" to "Move fast with stable infrastructure."
