I think people look in AIBU for a good old bun fight and/or light hearted debate and often do not have expertise to dish out proper wll thought out advice, not always true of course but I would say on the whole and it is generaly a matter of opinion. They will generally get a much more thought out and gentler post in the appropriate section as there are many regular posters who know alot about a given topic on the specific board.
can I just ask on the active threads it is alphabetical order and AIBU obviously is generaly shown on the first page. Do people automaticaly hide threads they are not interested in so to show a wider range in active threads? I did try this the other day but didnt actually view many threads as I was too busy hiding.
maybe chat is a better place for non descript or seeking quick answers threads.
Or we could request a quick fire round section?
