If Facebook were a country, it would be the 8th most populated in the world, just ahead of Japan.

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.

This is our commitment to users and the people who use our service, is that Facebook's a free service. It's free now. It will always be free. We make money through having advertisements and things like that.

The unsupervised learning is the way most people will learn in the future. You have this model of how the world works in your head and you're refining it to predict what you think is going to happen in the future.

Facebook is all about information and helping people share it.
