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.
Humor has always been important to me. If there is a shield of faith that you can keep up against difficulties, humor is the Teflon coating.
