Have a look at this though: https://steemit.com/steem/@jerrybanfield/introducing-steem-power-backed-smart-media-tokens, the first two comments have high vote value, but are against the post, so it would need to factor in commenters who flag the post etc. There's no simple algorithm I don't think.

This view is only updated every 10 minutes too, as the Steem API is not great for this kind of thing at the moment.
