Problem: We are finding many discussion posts solutions that either are exactly the same as a previous solution on the same question or slightly different and in addition they are being marked as solutions. This doesn't help the community if there is no premium on either expanding significantly on the previous answer or answering completely differently but also correctly. Users are being rewarded on just posting an answer not on posting a thoughtful, useful, and correct answer.
Solution: Stack overflow as an example handles this quite nicely in that they offer many different responses but also with the ability to upvote OR downvote a response. This would radically improve the responses along with the metrics that guide many other programs in play on the community.
