Facebook is uniquely positioned to answer questions that people have, like, what sushi restaurants have my friends gone to in New York lately and liked? These are queries you could potentially do with Facebook that you couldn't do with anything else, we just have to do it.

The days of you having a different image for your work friends or co-workers and for the other people you know are probably coming to an end pretty quickly. Having two identities for yourself is an example of a lack of integrity.

There have been misperceptions that we're trying to make all the information open on Facebook, and that's completely false. There are big buckets of information that we recommend that you share with only your friends privately. Then some of the more basic information, we recommend that that's visible to everyone.

A squirrel dying in front of your house may be more relevant to your interests right now than people dying in Africa.

In a recent survive of Millennials around the world asking what most defines our identity, the most popular wasn't nationality, ethnicity or religion. It was "citizen of the world." That's a big deal. Every generation expands the circle of people we consider one of us. And in our generation, that now includes the whole world. This is the struggle of our time. The forces of freedom, openness, and global community against the forces of authoritarianism, isolationism, and nationalism - forces for the flow of knowledge, trade, and immigration, against those who would slow them down.

There is something wrong with our system when I can leave here and make billions of dollars in 10 years while millions of students can't even afford to pay off their loans, let alone start a business. We all know you don't get successful just by having a good idea or working hard. You get successful by being lucky too. If I had to support my family growing up, instead of having the time to learn how to code. If I didn't know that I was gonna be fine if Facebook didn't work out, then I wouldn't be standing up here today. And if we're honest, we all know how much luck we've had.

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.
