When we were a smaller company, Facebook login was widely adopted, and the growth rate for it has been quite quick. But in order to get to the next level and become more ubiquitous, it needs to be trusted even more.

We talk about this concept of openness and transparency as the high-level ideal that we're moving towards at Facebook. The way that we get there is by empowering people to share and connect. The combination of those two things leads the world to become more open.

Facebook was not originally created to be a company. It was built to accomplish a social mission - to make the world more open and connected.

I don't have an alarm clock. If someone needs to wake me up, then I have my BlackBerry next to me.

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.

The thing that we are trying to do at facebook, is just help people connect and communicate more efficiently.
