On the right side of any question you can see the "Related" questions, which are questions that the system deems similar to the one currently asked.
If the question body contains links to other questions on the site or someone comments such links they are placed in a similar list above the "Related" questions in an area for "Linked" questions.
I just noticed that these lists can contain the same links. Why is that the case? If a question is linked it should logically follow that it's in some way related to the question asked, otherwise there is no reason to link it. I think it would be more useful to make these two lists distinct by excluding the linked questions from the pool of possible questions that may appear in the related questions so that more questions can be shown that may be relevant to the reader.
I couldn't find anything about this behaviour being intended.
Why can these lists contain the same entries? Are there older discussions about this topic that would explain why this behaviour is the intended one?
