The related-questions is an automatic part of stackexchange. The scripts gather a list of questions that are similar to the one being asked.
At the same time, there are many comments like:
<another stackexchange question
It doesn't seem like the list of related questions is utilized to its maximum potential in its current state.
Add up/down-vote for "relatedness" on related questions. This would be independent of the voting statistics on the linked questions.
The automatic list is good as a starting point. It updates itself over time with new questions. If there was a system in place that would allow an opinion on the related questions, then we could truly get related questions.
For example, if Question A is about CSS selectors, and Question B in the sidebar is about HTML forms, Question B could be downvoted on Question A's page to show that they aren't all that similar. But if Question A is about jQuery
setInterval, and there is a question on how to do
There are several possible layouts, one idea is:
Manual additions to the "related questions" list. This may not be necessary, if the comment's link is added automatically anyway. However, the comment receiving upvotes then should be also added to the "relatedness" upvotes, perhaps.
It would count the relatedness like this:
question Q1, related question Q2. Q1 has 3 upvotes. Q2 has 49 upvotes. Q2 is listed as "related" in Q1.
There is a relatedness count between Q1 and Q2: "Q2 is related to Q1 with weight of n" where n is modified by individual upvotes.
When you/a user vote on that Q2 is indeed related to Q1, that n gets incremented.
There could be several layouts for this, I made 4, but I'm sure a designer can do better:) :
v2, left (+ shift-to-inline)
