Alright, back.
If you're going to hold the idea of vox populi as the pure motivation behind using the system that you are using as you are using it, especially when you take into account, your, individually, Josh's perspective that people come in the flavours of agreeing with me and misinformed and ignorant, then lean on the authority of your own ability as a trainer in an unrelated position, I do not think that your argument is strong.
If 'more people like it' is a good metric for you to use as a reason to keep the system, then you should really shut the fuck up about Burning Wheel (because it's less popular than D&D 4E), and you should also start singing the praises of WOD (because it's still the second biggest elephant in the pen).
Obviously, you don't and you won't and it's a stupid rationale. My objection to the system is that any numerical rating system operates on a very flawed idea that you can quantify opinion. Not every opinion is the same. A game that's a 3 for me might be a 10 for you. What about if I have a high threshold for fan canon? What if I like a particular art style? All of this plays into the problem of a unified scale for an unified thing.
Have an opinion, say it, and don't try to tie it all up at the end with a rating system. People can make use of it doesn't seem to be as good an analogy to me.
Look, I guess it boils down to this: The reviews of material I've gotten from Yahtzee and Penny Arcade have been miles better than the reviews I've got from here, IGN, or even my beloved PC Format. If you can't articulate your opinion in a useful, meaningful way for your listeners or readers without a numeric system there is a problem deeper than a numeric system, and no system is really going to do anything more than push dirt over that problem.
Oh, and yes, they make the reviews lesser for me, because they both increase your laziness (we don't have to explain ourselves too well, because the number at the end will do that for us, such as demonstrated by your terrible set of reviews ending in Bullshit, Fullashit, Crockashit and Totalshit rating system or whatever the fuck it was), because they require qualifications (if you're going to do a steampunk game, this book is a 1!), and because it's like having an interesting scientific paper at the end decide to talk seriously in favour of flat-earth theories.
