When voting to close as duplicate, the system automatically creates the "possible duplicate" comment, with a link to the possible duplicate question. However, it fails to add a "linked question" to the Linked section to the right.
Take this question as an example. Screenshot:
When the necessary amount of close votes have been cast, the system automatically creates the "Possible Duplicate:" box in the question body. When that happens, the Linked question is properly associated.
I think it should still create the Linked question when the autogenerated comment is created. That way, visitors to a question that isn't completely closed will still plainly see the link.
Mainly, it's a matter of consistency. Why shouldn't every linked question be counted equally?
Furthermore, I believe this feature would serve two purposes:
- Visitors trying to solve a specific problem will be flipping through pages as fast as they can to find a solution. If they come across a question with no answers, they are not likely to bother to read the comments. In the most likely case of one linked duplicate question, only a single link will appear under "Linked". This will stand out more than comments. If they see a similarly titled Linked question (or "duplicate" question), they might click it and find their solution.
- Quickly glancing under "Linked" will help moderators and users that can cast close votes to determine whether the question is duplicate.
