History of Idea
Currently any post can be closed as a duplicate of other posts. Sometimes those other posts are already duplicates so chains start building up.
This leads to a mess like this:
C => B => A D => A B => A A => E
E is the original post. I was about to sugest to let all posts point to E directly, so that all the users won't have to click through the whole chain.
Then i found this: Avoid chaining "exact duplicates"
The main argument there was: There might be something helpful in the middle chain segments. I agree with this argument. In fact i agree so strongly that i want to suggest to let the original posts link back to all the posts, that point at it as in duplicated by or similar. This would increase the chance of of finding a correct answer in a short amount of time (and improve SEO i guess).
for the example it can either look like this:
// simply point back // double ended arrow for links on each other C <=> B <=> A D <=> A B <=> A A <=> E
or more sophisticated:
// point on everything that points to me, directly or over several levels // longer arrow to mark backlinkt C => B => A D => A B => A A => E A ==> B A ==> D A ==> C E ==> A E ==> B E ==> C E ==> D
What does the Community think?
Edit: I am speaking of exact duplicates, not subsets of a larger question.
