What's the right way to post a self-answered question on a topic which underlies many existing questions?
Consider in particular a case wherein many questions have been posed about Topic X. These questions are not particularly well written because the askers are not themselves experts in Topic X and so don't really know what they're asking about. Answers have been given, but for the most part suffer a lack of precision inherited from the relatively aimless nature of the questions themselves. How does one post a self answered question on Topic X, designed to provide a clear and unifying response to those poorly posed questions, without violating the duplicate rule?
