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.

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.

Even the simplest tools can empower people to do great things.

There's a lot of social input when you put these things out there. People's ideas cross with other people's thoughts.

The most rewarding thing for me has been this affirmation for me that people are basically good and smart, and if you give them a simple tool that allows them to exhibit that behavior, they'll prove it to you every single day.

Timing, perseverance, and ten years of trying will eventually make you look like an overnight success.

I mean just look at haiku, the idea of it. We want to focus on that singularity, on that simplicity, but we still want to add features and add value, but we want to do it in a way that fits in with that mentality of simplicity. You have to spend a lot of time thinking about it.
