Since questions that are closed as duplicates may have answers, I think it would be great if:
- the target (non closed) question gained a link to the dupe (ideally in a "duplicates" section with an indication of how many answers it has)
- the target (non closed) question was bumped to the front page
I believe the first request is sort of in place on meta where we have two way "linked" relationship - this is not the same as a Duplicates section however.
The second I haven't seen mentioned before and I think it would be good.
What will happen to the bumped B when it hits the front page?
- it may be edited. I see a number of "B"s in the review queue that are really crappy as questions. Yes, they ask the same thing as the "A" I am reviewing, but they are full of meta talk, badly formatted etc. Some days I use the history link in the review queue to go make the "B" better, some days I don't. If B was bumped, other people might take a look at it and clean it up if it's starting to become an important repository
- it may gain another answer. Apparently this is a problem that recurs and that many people face. Let's see if it has all the answers it needs. It's possible B has a perfect answer, but then again whoever asked A didn't come across B and has a problem to be solved. Like any edit to B, it may lead more people to read it and perhaps to answer it.
- it may gain views, or votes. It deserves those, since it was written well enough to attract at least one reasonable answer and it's now serving as a dupe-target
