I often find it hard to find back the old answers that fit the most popular "duplicate".
What do you think of creating a Meta that would be updated (when needed) and would contain all the links to the most popular questions/answers we use as duplicate?
This could be a featured Meta so we could all have a quick access to it. That would make it easier to close-as-duplicate sometimes.
I'd make it simple and as a list. There could be more than one answer for each question.
