I couldn't find a duplicate of this.
In SO there are many questions which are exactly the same asked in many different variants and flavours and aren't closed as duplicates. Usually such questions will have plenty of answers, so may be that's the reason mods here don't want it to be closed. Once when I flagged such a question for moderator attention, the reply I got was "I think its better to let sleeping dogs lie". Ok, I have no issues with that.
My question is, how do I answer a topic or question which is asked as a separate question on SO, which is essentially the same as a previous question, if I have an answer not posted til now for it?
Here are the options:
Post answer in the oldest thread.
Post answer in the most visited/answered/active thread.
a. Post a link to my answer as a comment in remaining threads.
b. Post a link to my answer as an answer in remaining threads.
c. Duplicate my own answer as answer in every thread (But I have seen users discouraging this)
d. Vote for all duplicate threads to be closed.
Which should I go for?
