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.

A 'GQ' award is kind of, like, insane. It's a huge thing.

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.

And winning is a huge thing for me.

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

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