Welbog's suggestion (which I intended to convey and failed miserably at it):
You have over 175 +10k-rep users on SO. Why not add a flag that is like the moderator flag but is visible to +10k users instead of just moderators? A flag for littler things like retagging, closing or cleanup. I personally would respond to such flags when I am online, especially if it contained a little blurb about the complaint. The moderator flag would remain as a method of handling bigger problems, and moderators would be able to see the +10k flags as well. Or, rather, +10k users would be able to "promote" their flags into moderator flags if they need moderator attention.
This way we won't waste manpower because people "haven't got enough rep" to help, even if they wish to (because, let's be honest, flagging a post over a title edit just isn't gonna happen ).
