Yep Scawen, I know and agree with all that, except with that moderating is an annoying task.. I know what you mean by it, but I don't think it's right. Doing your best at something is all that's required for a clear conscience.. Why would you burden your conscience with something someone else did? Any time you spend time thinking about something else than what you want, is an amount of time not spent thinking of what you do want, and getting closer to it.
The only annoyance I would know would be not having clear rules to follow. Not being in your head to know your opinion on any given post doesn't leave many posts to moderate, but in that last thread, a fair number of them were obviously off topic.
Just moving all the posts devoid of bug reports or particularly pertinent suggestions to a separate thread wouldn't be either annoying or complicated; except for you, obviously, if it was done wrong.
It certainly would have helped at least a little, in this case.
Good luck with all that work..
