What is really needed are mods that are sanctioned to do the finger-wagging/post-moivng.
Some have become self-appointed mods but they are doing it as they read through the forum regularly, as opposed to being an assigned mod to a particular forum. This is the first time I’ve ever seen a forum that has only a single moderator, and it’s the company’s CEO ! If there were five or six mods spread out so each covers a couple of categories (ideally enough to ensure that each forum section has at least two mods), and they were regularly reading the forums and moving posts to their correct categories, then it wouldn’t be a big deal to add more categories.
Sadly, the population of a forum is almost never up to the task of policing their own categorization.
Honestly, I usually look at things based on “New” and “Unread” filters, so I rarely even pay attention to which category I’m looking at. It would be pretty easy for me to post something new and not know which category it is going into… though I make it a point to verify which category I’m in before I post.
