I do everything on my phone as a lot of people do.

All of my friends who have younger siblings who are going to college or high school - my number one piece of advice is: You should learn how to program.

I'm trying to make the world a more open place by helping people connect and share.

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

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.

I think that more flow of information, the ability to stay connected to more people makes people more effective as people. And I mean, that's true socially. It makes you have more fun, right. It feels better to be more connected to all these people. You have a richer life.

In addition to building better products, a more open world will also encourage businesses to engage with their customers directly and authentically. More than four million businesses have Pages on Facebook that they use to have a dialogue with their customers. We expect this trend to grow as well.
