I haven't heard of Librivox before, and I'm too lazy to actually check the site, but my thoughts: Upvote-only, no displayed view/play count. This protects the producers by letting them assume neutral reasons for low approval ratings–maybe everyone who does listen to their reading is just too lazy to upvote–while providing a mechanism to say, "This one was good." I could also see making the upvotes invisible and using some magical algorithm to convert raw numbers into a range from "no one has given an opinion" to "lots of people liked this".
