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

At Twitter, mobile is in our DNA ... For us, it's all about mobile, and it always has been.

People first. Technology second.

When a plane lands in the Hudson and there's a Twitter user on the ferry taking a picture of it, Boom. That's it. The water is still splashing. Here's the photo of the thing.

When you think about email or IMing, why aren't you writing back? I can see your avatar, I know you're online, why aren't you writing me back? But with Twitter, everybody sends their responses to Twitter, and Twitter then sends them out to everyone. So there's not this constant connection. You can be hyperconnected, then you can take a break for a couple days and it's fine.

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.
