Sounds heretical. But maybe better: Does Fedwiki really need to support a community of people, or can we rely a little more on thinking about how we federate, how we move content around?
I have a lot more books than friends, and when I'm working, I'm more interested in working with the ideas in the books than thinking about the authors as colleagues or part of My Community.
We have the emphasis mis-placed. It's not a community of people but a federation of content - or call it ideas, material, cards, pages and sites - anything but "knowledge", please.
