I usually get closed questions but the answers are often useful.
I don't see why "closed" as such is problem. I could interpret it as "someone asked this question and it's been answer, we're moving on".
Sometimes I find an answer on a random web forum - if the forum still permits answers, there will 20 or 100 pages to look through and the usually the only good things will be right after the question.
The web at scale is just messy and cruel.
