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'm curious about writing in the age of online publishing. Because nobody cares about good writing online.

The two things I use the most are the MacBook Air and my iPhone. Those are my two most-used gadgets that are dented, scratched and smashed.

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

When you hand good people possibility, they do great things.

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.

I think we definitely want to focus on the simplicity aspect because it's something that's built into the culture even here at Twitter. Constraints inspire creativity.
