Let's say a question is asked, which receives a few downvotes and suggestions that a question should be improved, then closed. The question is later edited by the OP, addressing some of the issues, with a request for reopening. The request is satisfied, and the question is reopened for further answers. Is it correct to assume that it is the responsibility of the users that have issued the downvotes to check the question and potentially change their vote, if the edit changes their evaluation?
If yes, do they actually do it in practice? What is the right way to act, both when asking such a question, and when deciding to downvote somebody else's question?
