And I'm sure there would be more efficient and effective moderation if for each topic there was an established, trustworthy and active user as moderator, who speaks the language better than anyone.
Of course it would be more efficient, but since moderators are paid I don't think that's going to happen. With that being said, I think that there's enough active people who would do the job for free like they are doing on many other forums but for that the whole system would have to be changed and each and every child board should have their own moderator (so they can manage the workload) and that kind of change is again not likely to happen.
