There are many posts about the importance of cleaning up questions, and the need for that is clear. But why would a question be marked as too broad when there is only one answer and it is a good one? It is not as if there is a disk space, server speed, or SEO concern. Wouldn't it be more respectful to the person who took the time to prepare an answer to mark the question for editing rather than closure?
Impact On Answer Author Morale
This trend of hyper-hold-and-delete is very annoying to those of us who like to provide assistance to askers. One might work an hour on a good answer (that intelligently responds to ALL of the principles and rules of the community) only to find the answer is on hold and will probably be closed.
Even if we see the points (broadness, begging opinions, inadequate prior investigation) and suggest a question answer, our time and effort is discarded FAR too often. Future readers cannot benefit from what we've written, and the interest in answering well is diminished.
StackExchange is a system of incentives. Is it the SE marketing objective to discourage thought and excellence in preparing answers? Of course not.
The question is whether there should be a TOO BROAD hold when there is exactly one answer and it received up votes. Perhaps there should be another mechanism.
Can the rep increment for a good edit of a broad question be raised?
