I hear you, Guyon. Problem is, the point at which diminishing returns happens for some mods is a whole lot sooner than it happens for others. There is no objective criteria for establishing exactly where that point occurs. From what I've seen however, the thinner the skin, the sooner it's reached . . . if you know what I mean.
I also understand why manufacturers' mods don't want to pass the buck by sending difficult threads to GKD or W&C even though they'd be way better off leaving the hard moderation jobs to the experts. And I agree that if there's substance behind the criticism, it should be acknowledged and dealt with. Again, however, some mods are better equipped to deal with it than others. And some mods can't address criticism because they can't speak for the company whose forum they moderate. As always, it's a matter of applying the right tool for the job.
I know the supermods have their hands full dealing with what goes on around here. But clearly something has to happen to prevent subforums from caving. Regardless of whose fault it is, every time a KAI or a Hinderer leaves, we're left with a black eye. I can't help but wonder if it wouldn't help to have subforum mods go through an apprenticeship period with a supermod. If they knew they had someone specific to reach out to when the going got tough, they might learn how to to navigate their ships successfully when our waters turn treacherous.
