We have a very active testing community which people don't often think about when you have open source.
If you think of the ideas of open source applied to information in an encyclopedia, you get to Wikipedia - lots and lots of small contributions that bubble up to something that's meaningful.
For me, open source is a moral thing.
I often compare open source to science. To where science took this whole notion of developing ideas in the open and improving on other peoples' ideas and making it into what science is today and the incredible advances that we have had. And I compare that to witchcraft and alchemy, where openness was something you didn't do.
I think, fundamentally, open source does tend to be more stable software. It's the right way to do things.
Open source can propagate to fill all the nooks and crannies that people want it to fill.
Empowerment of individuals is a key part of what makes open source work, since in the end, innovations tend to come from small groups, not from large, structured efforts.
Certainly there's a phenomenon around open source. You know free software will be a vibrant area. There will be a lot of neat things that get done there.
Al Qaeda is nothing more than a mutant supply chain. They're playing off the same platform as Wal-Mart and Dell. They're just not restrained by it. What is al Qaeda? It's an open source religious political movement that works off the global supply chain. That's what we're up against in Iraq. We're up against a suicide supply chain.
We're not done yet, but two things WordPress has been able to exemplify is that open source can create great user experiences and that it's possible to have a successful commercial entity and a wider free software community living and working in harmony.
