In a world that's changing so quickly, you're guaranteed to fail if you don't take any risks.

Hollywood has nothing to do with real life.

I think video is a mega trend, almost as big as mobile.

When I started Facebook from my dorm room in 2004, the idea that my roommates and I talked about all the time was a world that was more open.

People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people - and that social norm is just something that has evolved over time.

The biggest risk is not taking any risk.

I don't want to be in a situation where I have to leave some other commitment or worse I am rude and someone else has to support my stuff. I stopped coding for Facebook a while ago.
