I've been going around the site for the little bit and reading other people's reviews. There is something I don't understand. I'll come across someone's review, read it, and rate it. I've noticed that sometimes the rating at the top will say "Useful Review" with a pink meter. That's just an example, but lets say I thought it was extremely useful and voted. I'll see that 22 other people have voted it as extremely useful as well. Then that confuses me. Why is a review considered only "useful" if a majority of people found it to be different. Is it because the first few people only felt it was useful?
