How about a noob perspective.
This question has a related duplicate answer
Implies a possible exact duplicate, does not have ambiguity associated with words like might and allows closely related questions to be consolidated via the links such that a new user like me could peruse them all and determine if any of them actually work for my case.
If so I can't vote it up or comment on it which helps perpetuate this issue, since less feedback was given or accepted. Reason, If I am unable to vote or comment and it is the answer I will likely never return once I applied the answer to my situation.
If not I am forced to make a new possible duplicate seeking help on my specific case, which helps to perpetuate this issue if I am so new that I have no clue if it is related to some other answer that is not marked This question has a related duplicate answer
You could put multiple related questions and answers together each linked with This question has a related duplicate answer even if overlap happens thereby consolidating them quickly. Tags would consolidate as well. Providing a noob or an experienced user to find related issues and possibly determine if there is a bug related to the question faster.
Remember as a noob I might not even know the correct tag or category of systems related to my issue to even ask the right question. Therefore noob questions that are broad spectrum could be consolidated into a very helpful set of focused questions and answers for noobs and experienced users could help focus the direction of these consolidated nodes of related helpful material.
This is an exact duplicate should bot be used because extremely qualified persons can have a tendency to place related questions and answers together with a quick peruse of key words and possibly not seeing some non key words that make it unique.
