Personally, I find the Amazon rating and review system very helpful and use it frequently. I only encounter Joke comments on things like 23 million dollar books or 10 thousand dollar A/V cables. I appreciate how verbose Amazon allows you to be in your comments as well as the ability to include images. I find rooting through the junk (jokes, paid comments, that guy who just received the product in the mail and either hasn't even used it or just begun using it and shouldn't really be commenting yet) is fairly easy too.
