Appropriation is the idea that ate the art world. Go to any Chelsea gallery or international biennial and you'll find it. It's there in paintings of photographs photographs of advertising sculpture with ready-made objects videos using already-existing film.

I mean we've built a lot of products that we think are good and will help people share photos and share videos and write messages to each other. But it's really all about how people are spreading Facebook around the world in all these different countries. And that's what's so amazing about the scale that it's at today.
