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.

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.

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.

Inventing your dream is the first and biggest step toward making it come true.

We hired a CSR person at Twitter, years before we hired our first sales person, to make sure we had a culture and impact of doing good.

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

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.
