Sometimes questions are closed as a duplicate of a question with an answer that isn't as clear as it could be.
If this is the case, should new answers be posted as another answer on the original question? Or should the closed question be reopened and answers posted there?
For example: Add a pause to an animated camera (following curve path)
If answers are added to the old question, all the answers stay in one place, however the answers will likely be conflicted in trying to address the nuances of the new question while acting as an answer to the original question.
If answers are added to the new question, answers are split into separate posts, but the answers stay where the action is and are free to address the OP's exact situation directly. Plus any comment discussions with the new question's OP will be in a more relevant location.
Which is preferred?
