(As of before I made the title twice as long but more specific - you should read my function names!) my question is a duplicate of

However our business logic has changed so much since then and since I find the logic in the original questions obsolete I'm re-raising this. As I have argued all over the place and there is some consensus on, duplicates are much more like valid questions that happen to be answered somewhere else than they are like close-candidate questions. I'm putting this in bold since it is okay to re-open feature requests if there is a reason things have changed (and also here), and our current most official stance on duplicates being warmly received comes from November 2010, more recent than either of the questions above. The reasoning:

  • The OP can accept an answer unilaterally. Shouldn't the OP be able to unilaterally accept an answer on a linked question, viz., close as duplicate?
  • If the question turns out to be a duplicate the OP has no way to indicate the question is resolved until at least 5 users have participated. Those 5 users should not have had to drill into the question to figure this out, much like accepting an answer.
  • In general all the reasons accepting answers is important, apply perfectly well here.

    Yes - I would like to be able to do this with my own questions - especially here on Meta.

  • what if community disagrees with OP and decides to reopen the question they closed (5 reopen votes or 1 from moderator)? Would you expect OP to be allowed to unilaterally re-close it again?

  • @gnat good point. don't allow. exactly analogous to "what if the community disagrees with the accepted answer?"

    @benisuǝqbackwards I think that's a valid dupe, but it's... kind of long.

  • You don't need to read the entire thing @djechlin, everything you mention is covered in the first 5 sentences, all nicely spaced. Jun 6, 2013 at 16:53

    @benisuǝqbackwards okay fine. Voting to close my own question as dupe. Before someone points out the irony, I'd like to argue that this in fact, not ironic.

  • Of course it's not ironic, that's the point of our requests :-). Have an upvote because I agree with you! Jun 6, 2013 at 17:05
