Although I have been with the wider StackExchange community for a number of years, I still consider myself inexperienced when writing posts on math.SE. Today, for the first time, a question I posted was closed. The reason I received was generic: "Add details and clarify the problem you’re solving". I always strive to post clear and detailed questions, and I am always interested in improving my writing.
However, having reviewed the Help Center article, it is still not clear to me which aspects are in need of improvement the most. Notation? Rigor? References?
And I don't believe I am, or will be, the first to face this issue. Is it possible to have a process where close voters leave feedback for the OP, if such feedback has not been mentioned by a previous voter? I think this will be very helpful to the OP, and the community in general, in raising the quality of posts.
