Perhaps editors should have their status revoked after a random period of time, to keep things fresh? I suppose the problem with that is ensuring that the system 'promotes' enough normal users to fill the gap; again, random assignment might work.

People might be keener to be active editors if they receive an unexpected invitation to participate, but with the understanding that it might only last a week.
