Of course, hate speech and racism have no place on Facebook

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

People wait until late in their career to give back. But why wait when there is so much to be done?

It is important for young entrepreneurs to be adequately self-aware to know what they do not know.

By giving people the power to share, we're making the world more transparent.

I mean, we've built a lot of products that we think are good, and will help people share photos and share videos and write messages to each other. But it's really all about how people are spreading Facebook around the world in all these different countries. And that's what's so amazing about the scale that it's at today.

Facebook is inherently viral.
