I second that about the reviews, I see currently two problems:
1) Reviews by people not having bought this product on Amazon
Really, wtf? Why should I care about someone reviewing it who hasn't bought it *there*? Doesn't make sense to me. If I want to get a general review of a product, I need to got somewhere else, ideally where you don't buy it, period.
2) Reviews of similar items mixed together
Search for some random DVDs with BluRay counterparts. Or VHS. You'll suddenly find people reviewing/rating the product (e.g. I'm looking at the BluRay entry of the movie), the talk about the bad quality or something about the content and it's only until later you realize: they talk about the DVD or VHS version. Wtf? Again, IMHO that's complete BS to me.
