Question votes not reflective of total votes on all answers to said question
Maybe I am missing something, but I am reading this thread: Why are questions not being voted on?
I am wondering, if a question is already answered, why not make up-votes to the answers give a fraction of the vote to the question? After all, if a person found the answer helpful, doesn't that mean that the question was pretty helpful too?
Maybe it doesn't need to be visibly-upvoted, but at least for the purposes of ranking that should be quite similar. What else is the question rating used for?
