There are a lot of rich people in the world. There are very few people who have the privilege of getting to invent things that billions of people use.

I'm very antischedule. Except for board meetings, I don't really schedule things or keep a calendar. I think appointments are caustic to creativity.

Today there are millions of people making stuff and putting it into the world: that's become part of our identity and it shouldn't be limited to people who fancy themselves writers, or who are particularly witty or talented.

Reading for me will be a combination of books, magazines, Tumblr, and just kind of the Web in general on the iPad.

Where I feel the most productive and engaged is when I'm buried in code, buried in some project, tweaking some designs. I'm certainly introverted.

For every new feature we add, we take an old one out. A lot of big sites don't do that, and it's a problem.

Every feature has some maintenance cost, and having fewer features lets us focus on the ones we care about and make sure they work very well.
