I'd rather see something like a ratio of upvotes to actual page views as a measure of how many people actually READ a given piece of content.

Unfortunately, I'm not aware of any way to get page views - especially given the possibility for views through multiple front-ends. Your suggestion made me think that I could get payout per feed placement, though (based upon the "feed-reach" number, above). Not as good a payout per view, but maybe a step in the right direction. I might add that metric. Thanks for the feedback!
