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

Apple is in a position they've been in a lot of times before. They're like Moses showing the way to the promised land, but they don't actually go there.

Think of how Wikipedia works, how Amazon harnesses user annotation on its site, the way photo-sharing sites like Flickr are bleeding out into other applications. We're entering an era in which software learns from its users and all of the users are connected.

There are more than 21 eBook channels already. Authors can’t possibly get to these and do what they do best.

Life is not a tour of gas stations.

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.

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