If anything, that would be a tag, not a section. That is, someone might tag a question as interesting for beginners, or maybe for experts.

In any case, having experts solve the basic stuff is wonderful. One, it gives expert advice to beginners, so they get it right straight from the beginning. Two, it helps the experts by giving them constant review of the basics. Too often "experts" create elaborate solutions because they forgot (or never learned) some (rarely used) simple feature.

It even helps beginners who attempt to solve complex issues, because it makes them think. People can easily walk away when they realize the problem is too advanced for them, but until that point, thinking about the problem is helpful in overall skills.

There might be some benefit to categorization, though i don't think it would be worth the losses.

Right; I don't think the OP was suggesting the use of sections; I only see mention of categories.

I reckon we are the only monastery ever to have a dungeon stuffed with 16,000 zombies.

Hmm... Now that you point it out, i see where you could translate it that way. Though, "a categorization of questions" still sounds to me like some form of sectioning.

Eh, it's not like it matters anyway. :)

It does not matter, read out what problem the expert has, if you are able to give solution that's fine, otherwise no problem, others will give the solution and read those and learn and become expert. All the Very best.
