"Trust me, I know what I'm doing." Just how valuable are the user reviews on Amazon.com, IMDB, etc.? Remember, these are the same people who send you spam, MAKE.MONEY.FAST messages, virus hoaxes, urban legends they swear are true, Bill Gates/Disney email tracking giveaways, and all sorts of other crap. Are these the people you want to recommend books and web sites to you? And how do you separate the idiots from the net.gurus?
