Well, the rating system is voluntary, and stories may not get reviewed, or only by a single person who has an axe to grind. I saw one last night that had five ratings from 8 to 10, and one idiot who gave a 2 with the notation that they didn't like stories on that subject. If the idiot had been the first reviewer, how many other people would've taken the chance on a story with a 2 rating?
