I previously asked this on Space Exploration Meta as Should we do anything for answers on duplicate questions?. The basic train of thought is as follows:
- A question was closed as a duplicate. During the vote-to-close an answer was added. After the question was closed, discussion continued on that answer for ways to improve it.
- Given the seeming reasons for voting-to-close as a duplicate, it seemed to me that spending effort improving an answer to a question that was not likely to be re-opened would be better spent improving answers on the question we point people to.
Am I even correct about the reasoning for closing duplicate questions? If so, is it worthwhile to try to concentrate useful answers to those families of questions after-the-fact? Or is the status quo where all of these questions should be linked to each other and they can be visited and checked to see if they have useful answers good enough?
