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.

My own personal dream is that the majority of the web runs on open source software.

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.

I am the unhappiest WordPress user in the world, I think it sucks.

A common quality I see of people who are successful is that they are voracious readers.

The relationship between WordPress and Tumblr has always been pretty friendly: Tumblr's own blog used to be on WP, WordPress.com supports Tumblr as a Publicize option alongside Twitter and Facebook, our Akismet team sends them daily emails of splogs on the service, and there's healthy import and export traffic both ways.

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.
