How about an automated email to the OP with suggestions on how to improve the question if the question gets no traction. Sometimes short questions are very clear and require no more details so you can’t just base it on length.
The other possibility is that a moderation option include “send advice/suggestions to OP”. That way contributors don’t waste time trying to extract additional details and it’s really up to the OP to add details or not.
As for StackExchange, I find their approach to be too far to the other extreme. You get flamed, downvoted or both for even the slightest transgression. The regulars seem to take more pleasure in stepping on people rather than actually helping them. It’s not a pleasant environment :>). Basically it’s an expert site that helps other experts.
iFixit is quite the opposite and kudos to @oldturkey03 and @mayer for making (and keeping) it what it is.
