I think redundancy is an important factor here as well. That was an issue I saw frequently on subreddits and a primary reason for me disengaging from those communities.

You would see the same low effort question posed with other users responding with high effort/detail (albeit redundant) answers. Regardless how well constructed the feedback might be, that response is dragged down by the lack of effort inherent overall to the post.

If nothing else except for the sake of space saving, a large percentage of those posts could have been nuked with no real impact to how readily the subjects/solutions could be found.
