I started the site when I was 19. I didn't know much about business back then.

If there is a bug in your code than you have to drop everything you're doing and go fix it.

It used to be the case, like, you'd switch jobs, and then maybe you wouldn't keep in touch with all the people that you knew from that old job. Just because it was too hard. But one of the things that Facebook does is it makes it really easy to just stay in touch with all these people.

Virtual Reality is going to be an important technology. I am pretty confident about this.

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

This is a perverse thing, personally, but I would rather be in the cycle where people are underestimating us. It gives us latitude to go out and make big bets that excite and amaze people.

It is really important for us that people understand what the strategy is and that the real approach is to make everything social, not to build a vertical approach.
