What Facebook stands for in the world is giving people a voice and spreading ideas and rationalism.

One thing I have reflected on is that when I started Facebook, the mission of connecting the world was not controversial. It was kind of as if it was a default assumption that people had - every year the world got more connected - and that seems like the direction that things were heading in.

Connecting the world is really important, and that is something that we want to do. That is why Facebook is here on this planet.

Google, I think, in some ways, is more competitive and certainly is trying to build their own little version of Facebook.

We think the fact that Instagram is connected to other services beyond Facebook is an important part of the experience...This is an important milestone for Facebook because it's the first time we've ever acquired a product and company with so many users.

I updated my grilling app, iGrill, today and it now has Facebook integration that lets you see what other people are grilling right now around the world. Awesome.
