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

We actually created Twitter and Odeo at the same time. When we realized we didn't really want to be running Odeo anymore we looked around for anyone who wanted to buy Odeo, but not acquire us as a technology. But people aren't as interested in that.

Investors are employees you can never hire. We made sure to pick investors that thought like us.

You can shut down a service, and yet people will find ways to communicate.

I think before Twitter people didn't think that way, not in any sort of meaningful or specific way, so what I'm trying to say, if we're trying a bunch of stuff, a lot of cool and great social stuff, a lot of platform stuff, then some of it will stick, and some of it will be junked over. Some of it will be just like the cell phone, you can't imagine not having it.

With Twitter, it's as easy to unfollow as it is to follow.

The reason I really started running was for meditative purposes. I would pick some problem to have in my head while running.
