> I usually search for reviews written by people who have had the product for a week or two and give the pros/cons along with a less than 5 star rating. That helps me avoid the fakes and the idiots.

Might only help somewhat with the fake reviews. From the "Avoiding Detection" section:

"Fraudulent businesses give reviewers specific criteria to follow to avoid detection on Amazon. These criteria are designed to present the reviews as legitimate. In this ElasticSearch server, vendors asked reviewers to wait a few days before publishing a review. They also request substantial reviews that are longer than just a few words, and may even outline certain details that should be included in the review."
