Mobile is a lot closer to TV than it is to desktop.

I personally don't invest in a lot of companies because I think it would be a conflict of interest and Facebook doesn't typically either.

We should have a society that measures progress not just by economic metrics like GDP, but by how many of us have a role we find the meaningful. We should explore ideas like universal basic income to make sure everyone has a cushion to try new ideas.

I try to shrug it off as a minor annoyance that whenever I do something successful, every capitalist out there wants a piece of the action.

We want Facebook to be one of the best places people can go to learn how to build stuff. If you want to build a company, nothing better than jumping in and trying to build one. But Facebook is also great for entrepreneurs/hackers. If people want to come for a few years and move on and build something great, that's something we're proud of.

We have a pretty ambitious goal for the world. What we think will make the Web better. What we think will make all these businesses that integrate with us run more effectively. I think if we stay focused on doing that, that's really the main thing that we need to do.

Every application will be designed from the ground up to use real identity and friends.
