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.

You have to think for an email. What's the subject? What's it about? It takes two seconds to think about that. So you have to think, Is this a work thing or a social thing? Which? Then you get into a situation that you don't want to be in, because then people are thinking about it too much.

I started out as an artist, and I continue to think of myself as an artist first, and a technologist and entrepreneur after that.

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.

When I studied graphic design, I learned a valuable lesson: There's no perfect answer to the puzzle, and creativity is a renewable resource.

A Twitter update is simple and fast and gets the information and news, and it spreads it very quickly, and it can contain links so you can then link to this whole context of information.

I think Twitter has brought something totally new to the table.
