Not every community will have someone with as much spare time as you Mr. Wookipedia Mod. I've seen various Discussion boards derail very fast because there are not enough mods, or they are simply not interested in monitoring that feature. How do you fix that?

I don't think the the "Sub-Community" of Discussions are hurting wikis, but rather they are not helping it in any way.
