It's tough to say, exactly, what things will look like in three to five years, but there's a lot of work to do in just moving along the path that we've already set out.

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.

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.

In terms of doing work and in terms of learning and evolving as a person, you just grow more when you get more people's perspectives... I really try and live the mission of the company and... keep everything else in my life extremely simple.

The question isn't, 'What do we want to know about people?', It's, 'What do people want to tell about themselves?'

I think I've grown and learned a lot.

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