I'm fascinated by simple joy.

Trust is a confusing thing. It seems so simple, but when you try to pin it down, it can be so elusive.

I've been fascinated by the Internet from the very start. In 2001, I had made a funny black-and-white film called 'How to Dance Properly,' a short video of me dancing to a Madonna song. I sent it to 17 of my friends on a Thursday, and by Monday, one million people a day were logging on to view it.

What's so funny about cats is that they have this kind of aloof, superior vibe to them. Even if you love them, they are unpredictable. Dogs are more social, and the way that they attach and bond to us is much more human.

Mobile video is now a reality and a force to be reckoned with. I think it is essential to think about how people interact with their phones; how they consume content and how they share.

I've been super impressed with what BuzzFeed has done on Facebook with inspiring list posts and on Twitter with political scoops, but YouTube is a giant social platform that has its own quirks and oddities and will require some new approaches.
