I recently answered a question on SO that was marked as a duplicate:
However, the question was marked as a duplicate of another question. No problem, except that the question in question is closed:
In this case, I suppose the askers already got most of the information they need, and additional answers might not help too much. But in general, this seems like a bad idea, because both of the questions are disabled in some way, so no one will be able to interact with either of them. If someone came upon these questions and had a better suggestion, they wouldn't be able to post on either question.
Isn't that a suboptimal situation?
