I have to say there are a lot of me-too products and companies. Yet another social network, of the 15th flavor - that's common in every new technology revolution. There are imitators who have marginal improvements.

What new technology does is create new opportunities to do a job that customers want done.

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.

We don't market products narrowly. We market big stories about the industry, things that matter to a lot of people.

With social media and all the new technology, there's just more interfaces around and reminders to constantly be working on our body.
