When marking duplicates, shouldn't newer post be the duplicate of an older post and not the other way around?
How can a post from 2012 be a duplicate to something from 2013?
I only ask since the duplicate message is:
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
So how can a 2013 have already been asked before a 2012?
