At Twitter, mobile is in our DNA ... For us, it's all about mobile, and it always has been.

We didn't have anything before Twitter that allowed a group of people roaming around a city to communicate instantly, in real time, and in a coordinated way, in a group.

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.

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

The normal press cycle is to put a company on a pedestal and then knock it down. It's much more interesting that way.

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.

Lesson number one: opportunity can be manufactured. Yes, you can wait around for the right set of circumstances to fall into place and then leap into action but you can also create those set of circumstances on your own. In so doing, you manufacture your own opportunities. This has helped me immeasurably.
