Twitter is the ultimate service for the mobile age. Its simplification and constraint of the publishing medium to 140 characters is perfectly complementary to a mobile experience. People still need longer stuff, but they see the headline on Twitter or Facebook.

Technology is closing the gap between what one can imagine and what one can do and as a result the equality of opportunity is unmatched in human history.

Do what you love and don't focus on money - life's too short.

I'm an investor in MakerBot, which is a good example of the 'thingiverse'. The idea of applying collaboration and rapid iteration to things that we interact with and hold in our hands everyday is super revolutionary.

If I were to wish for two things, they would be as much bandwidth as possible and ridiculously fast browser engines.

I like to read first thing in the morning. I'm addicted to the Kindle. I read a lot of business books, because I feel like I should figure out how to be a real businessman before someone figures out that I'm not one. I really enjoy reading classics as well, which I try to work in once every two months.

The biggest motivation is not the money but the impact.
