Consider [this question](https://emacs.stackexchange.com/q/975/105).

I went to close it as a duplicate of these two [emacs]-tagged questions on StackOverflow:

* https://stackoverflow.com/q/14764130/729907
* https://stackoverflow.com/q/22479140/729907

I was informed that questions are not duplicates if they are not on this same site.

Is that the right policy? So we encourage users to duplicate the 8 zillion [emacs]-tagged questions on SO and SuperUser and...? *Why is this good?*

[This post on this meta site](https://emacs.meta.stackexchange.com/a/7/105) tells us: "*During the private beta: if you see an existing question* **which has not been satisfactorily answered** *and that interests you personally, then feel free to re-ask it here.*"

Maybe that's good. Maybe not. (FWIW, I see no good reason given in that post for such a policy.)

But suppose it is good. What about questions elsewhere that **have good answers** there? The above policy specifically calls out the criterion that the question elsewhere ***not*** have a satisfactory answer, so presumably duplicate questions with satisfactory answers (perhaps even accepted) should ***not*** be duplicated here.

And yet they are not to be closed as duplicates. Does this make sense?

[Update 2017-05-26] Here's [another one](https://emacs.stackexchange.com/q/33068/105). Surely there ought to be some way to consolidate such questions - move them here or be able to close duplicates here.

[Update 2019-01-11] FWIW - For cases where the same person poses the same question here and on SO (typically at about the same time), I've been entering a comment for each question, asking that they post to only one of the sites: pick one and please delete the other.  I think 100% have then done that.  That helps to (1) concentrate answers in one location and (2) nip a bad habit in the bud.
