Build what you want to see in the world.

My goal is to simplify complexity. I just want to build stuff that really simplifies our base human interaction.

The interesting products out on the Internet today are not building new technologies. They're combining technologies. Instagram, for instance: Photos plus geolocation plus filters. Foursquare: restaurant reviews plus check-ins plus geo.

It's really complex to make something simple.

Great companies don't just have one founding moment. They have many founding moments.

TweetDeck is a very interesting client, because it presents a view that no other client in the world presents, which is this multicolumn, massive amounts of information in one pane. And people really, really enjoy that.

Making something simple is very difficult.
