Sometimes, an answer for a question A also works for a question B. While question A & B are different questions and are not really duplicates (as questions), but the answer is an answer for both. Should we just add a related comment or should we close as duplicate?
If an answer works for two different questions, should we mark the new question as a duplicate?
I think we need to be pragmatic - it won't be the same every time it happens, especially when when question is broader and the other narrower.– hippietrailOct 9, 2013 at 11:11
Questions should be closed if they are duplicates and not if the answer happens to be the same. There is also an official policy for this, but I can find it right now. However, I could find Joel Spolsky's answer to a similar question.
4So, since Joel Spolksy's answer applies to this question, can we close this question as a duplicate... :P– FlimzyOct 11, 2013 at 21:59
1I believe this blog post is the official policy you are referring to: blog.stackoverflow.com/2010/11/…– mtsMar 23, 2016 at 11:52
Somebody should vote to close; that will give the user the big banner. On SO, it's common as dirt for the question to be all wrong. They think the issue is "null reference exception" but it's really "product is looking in the wrong folder". So I will not hesitate to mark as dupe if the answers to A take care of B also.
Here, you might think a person knows if they want "how to get to the airport from XYZ" but you know, if the answers to "how to get from XYZ to the airport" work, then they work, right? So I won't mind if after that first vote-to-close, 4 more happen to come along. But you don't need to worry about 5 votes, only about your own.
