I suspect self-selection: Right now, Linux is the most popular Unix. If you're going to another system, there's probably a reason, either technical or ideological. But to know enough to know why you might want to move already requires a lot of technical knowlege. And the will to actually do it, stick it out, and learn the different ways the system works requires a certain willingness to learn (although the excellent docs DO help). It's not so much that you can't use the system if you're a casual consumer, it's that if you're a casual consumer, you won't bother. Also, it's not a bias: We're trying to root-cause why the freeBSD community is so knowledgable. if it's because only the most knowlegable are capable of using it, that isn't a bias, it's just a result. /nitpick
