There's absolutely a ton of room for improving review systems. Right now I have a fairly standard "how many stars + written comments" review set up on my startup (example link below), but I'm planning to test some ideas, such as giving people with different levels of karma different numbers of "points" to review with, to try to get the distribution of ratings closer to a standard bell curve. example link: http://www.parkgrades.com/parks/rio-montana-park http://www.parkgrades.com/parks/rio-montana-park
