I'm confused, isn't established standard too nebulous a concept to be "needs to be upvoted", there is just too diverse of an opinion on what what is a "well thought out comment" and one person's "inflammatory" comment could be another person's "well thought out comment", the cognitive dissonance is upstream of all the voting patterns and there can be no set standard except organic, binary up/down voting. I think the ideal is that on average the local maxima (upvote groupthink) eventually is balanced by local minima (downvote groupthink)... but I would like to see how an established standard could be set for what should or shouldn't be upvoted?
