You know, you really don't need a forensics team to get to the bottom of this. If you guys were the inventors of Facebook, you'd have invented Facebook.

We've changed our internal motto from "Move fast and break things" to "Move fast with stable infrastructure."

The primary things that people do on the Facebook is they use it to share with their friends and the people around them and their community, and they use it to keep in touch with people.

Our goal is not to build a platform; it's to be cross all of them.

I actually do think you're seeing this trend towards organizations just caring more about their brand and engaging. And so I think Home Depot will want to humanize itself. I think that's a lot of why companies are starting blogs, are just giving more insight into what's going on with them.

I think that people just have this core desire to express who they are. And I think that's always existed.

Facebook is inherently viral. There are lots of sites that include a contact importer, and for lots of them it doesn't really make sense. For Facebook it fits so well. It wasn't until a few years in that we started building some tools that made it easier to import friends to the site. That was a huge thing that spiked growth.
