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

We are working hard to build a service that everyone, everywhere can use, whether they are a person, a company, a president or an organisation working for change

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

Think about what people are doing on Facebook today. They're keeping up with their friends and family, but they're also building an image and identity for themselves, which in a sense is their brand. They're connecting with the audience that they want to connect to. It's almost a disadvantage if you're not on it now.

Advertising works most effectively when it's in line with what people are already trying to do.

[Facebook] is shaping a broader web. If you look back for the past five or seven years, the story about social networking has really been about getting people connected... But if you look forward for the next five years, I think that the story people are going to remember five years from now isn't how this one site was built; it is how every single service that you use is now going to be better with your friends.

Building a mission and building a business go hand in hand.
