Since people look at reviews to get an impression of what kind of story they're considering to read, the last thing an author wants is some opinionated idiot's review (who probably doesn't even know what in the world they're talking about) being the first one people see. So, why not have an option where the author can choose a single review that appears first? Sort of an "author's choice" type of deal, or how movies, books and other such things have a choice on whose criticism/review to add onto their cover (if any at all). While authors can certainly take advantage of it by choosing a review that's nothing but praise (which is normal in the professional world, anyway), people should be able to tell if it's real, constructive criticism or an empty attempt to put a positive spin on the story.
