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

Our goal is to make it so there's as little friction as possible to having a social experience.

The basis of our partnership strategy and our partnership approach: We build the social technology. They provide the music.

It wasn't until we got our first office in Palo Alto where things became more like a company. We never went into this wanting to build a company.

Our role is to be a platform for making all of these apps more social, and it's kind of an extension of what we see happening on the web, with the exception of mobile, which I think will be even more important than the web in a few years - maybe even sooner.

We're very focused on making News Feed really good, making our photos experience really good, making messaging really good, and creating great location apps. That's the nature of a platform business of our scale. Most companies that are relevant to us will have some overlaps in some competitive way.
