@Marmaduke: Problem with that idea is that popular mountains would for sure be the top rated pages. That's some what the case right now, but at least well made pages on obscure places have a chance. In the system your proposing, a bad quality but famous mountain would have a much greater score than some of the best work posted here on SP. Trust me, this would happen.
On the bright side that system would create far less complains and less drama. But it does not have enough score integrity. That is the entire reason for having negative votes.
