There are a few other things that I built when I was at Harvard that were kind of smaller versions of Facebook. One such program was this program called Match. People could enter the different courses that they were taking, and see what other courses would be correlated with the courses they are taking.

I'd like to show an improved product rather than just talk about things we might do.

Right now, with social networks and other tools on the Internet, all of these 500 million people have a way to say what they're thinking and have their voice be heard.

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

Whenever I go to a new city, in order to help get on the right time zone and actually get a chance to see that city, I like running.

Stuff like photos and events and groups - we've built pretty basic versions of those apps to start but they ended up being so much more used because of their social integrations.

What really motivates people at Facebook is building stuff that they're proud of.
