I mean, even when it's really simple, there's so much amazing beautiful creativity that can come out of that.

I don't think of Twitter as a social network. I think of it as a messaging system that has a lot of social components to it.

The future of marketing is philanthropy.

I got an idea: people like news why don't we write the news down on a piece of paper, and we'll gas them up and drive them to everyone's house. I mean, if you were going to say that now, it doesn't sound like a great idea, because there are other ways you can distribute the news.

Creativity is an infinitely renewable resource - you are not going to run out of it - so don't be afraid to use it.

The reason I really started running was for meditative purposes. I would pick some problem to have in my head while running.

The thing that excites me, and the thing that excited me about Twitter, is the idea of a flock of birds moving around an object in flight.
