If things aren’t breaking, then you’re not moving fast enough. People learn by making mistakes.

We want Facebook to be one of the best places people can go to learn how to build stuff.

I mostly built stuff that I liked.

If Facebook were a country, it would be the 8th most populated in the world, just ahead of Japan.

I think I've grown and learned a lot.

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.

I think there's confusion around what the point of social networks is. A lot of different companies characterized as social networks have different goals - some serve the function of business networking, some are media portals. What we're trying to do is just make it really efficient for people to communicate, get information and share information.
