We're entering a new world in which data may be more important than software.

The biggest mistake we see companies make when they first hit Twitter is to think about it as a channel to push out information.

Pursue something so important that even if you fail, the world is better off with you having tried.

The nice thing about twitter is the architecture of visibility. Email is invisible unless you reach out to someone directly. With Twitter, anyone can follow you and this is one of the big changes that was really introduced by Flickr, was this wonderful idea that you can follow somebody without their permission. Recognizing that relationships are asymmetrical, unlike facebook where we have to acknowledge each other otherwise we can’t see each other.

Create more value than you capture.

Money is like gasoline during a road trip. You don’t want to run out of gas on your trip, but you’re not doing a tour of gas stations.

The future is always scary to those who cling to the past.
