Moderation on something like that is not "difficult", it is irrelevant.
I don't understand what exactly in it is irrelevant.
At least participants experience of the thread is relevant, all of them.
Shy voices must be guided, maybe guarded.
Grumpy old men are not exactly a disappearing resource but their electronics can be.
More vocal folks will also always dominate, difference is only in contents.
Community moderation will work indefinitely if community stays homogeneous enough.
And fails instantly when heterogeneous goes over the tipping point, simply because different groups have so different demands.
Bringing up stackexchange indicates that your moderator is preventing things.
My moderator is maintaining things.
And Thread Topicness and Section Hierarchy Issues of Maintenance Hierarchy would handle nit pickers.
Community moderation of heterogeneous community can still work but then its homogeneous parts must be, at least partially separated.
If Other Communities here get Cars section it can finally and quite easily dominate the traffic of the whole place but would that be a bad thing.
Forums can also split under the same roof, so Dave would still benefit, I guess.
We seem to be in agreement!
My point was solely that on that thread there was nothing that needed either formal nor community moderation. It was trickling along nicely with the usual interplay of viewpoints. That is typical of this forum (unlike elsewhere) and is one of this forums strengths. OTOH if someone simply wants to cut and past "solutions" (usually overly simplistic and without comprehending them), then stackexchange is ideal - but boring and sterile.
Your "tipping point" divergence is relevant. History shows that all communities will evolve and have schisms. Whether they can coexist in different areas under the same roof is less clear. Often an
amicable split is the best option.
It is all shades of grey
