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.

In my home office, I have two large, 30-inch computer monitors - a Mac and a PC. They share the same mouse and keyboard, so I can type or copy and paste between them. I'll typically do Web stuff on the Mac and e-mail and chat stuff on the PC.

It's good to work for someone else. Because then you appreciate it more when you are an entrepreneur.

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 you're not embarrassed when you ship your first version, you waited too long.

From the first time I held an iPhone, the space has evolved quickly, and people have shifted from reading content on their desktops to smartphones and iPads, even long-form stuff.

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.
