Under the StackOverflow-as-Wikipedia model where it's a card catalogue of best answers, the right thing to happen is:

- they get marked as duplicates, so that all future people coming in via Google get funnelled to one place

- that place gets new modern, more relevant answers

- they get voted up because they're useful

- people add comments about answer compatibility

- they either overtake the other answers and the other answers stay around as history, or if they don't there is a single place where relevant answers can be found.

1 question with 10 answers is a lot more discoverable than 10 questions with 10 answers.

One leads to 9 answers to skim-read and ignore and 1 answer to use.

The other leads to you finding 6 questions and 6 answers you don't like and 0 answers to use and missing 4 you didn't know existed.
