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.

The rise of broadband and growing ubiquity of Internet access excites me the most. The world changes a lot when, no matter where you are - in the middle of a deserted highway or in a bustling city - you can get high speed broadband access.

One thing about open source is that even the failures contribute to the next thing that comes up. Unlike a company that could spend a million dollars in two years and fail and there's nothing really to show for it, if you spend a million dollars on open source, you probably have something amazing that other people can build on.

You can't build everything and there is no more a killer feature. Everyone has a different killer feature.

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

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

The biggest challenge for open source is that as it enters the consumer market, as projects like WordPress and Firefox have done, you have to create a user experience that is on par or better than the proprietary alternatives.
