Yeah, when a product has a lot of polar (5 and/or 1 star reviews) I often spend a few minutes looking into those people's other reviews, to see how they are. When there's almost no description and all 5 or 1 star, it becomes obvious pretty quickly that they are probably paid reviews.

It's a shame that Amazon can't just implement a weighting system with values based on how much a customer has purchased, how long they've had their account and the number and range of stars in reviews they've given. That would be a lot of map/reduce jobs over a lot of people, and reviews... but weighting the "overall" rating better would go a long way towards improving things for everyone.
