We realized we weren't really using Odeo, we weren't investing our own time creating podcasts. We were building a tool that was a great idea for some other people. That's a dangerous way to go because if you don't actually use it yourself and love it, then you aren't going to be as fully invested in it from the start. That's what leads you to doing side projects.

Creativity is an infinitely renewable resource - you are not going to run out of it - so don't be afraid to use it.

I think of Twitter as a messaging system that you didn't know you needed until you had it. Think about when cell phones first started coming out. People said, "Why would I carry my phone around?" And now you'll drive back to your house thirty miles if you forget your cell phone.

Creativity comes from constraint.

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

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

In any leadership position, you're always going to be disappointing somebody.
