I agree too, that most reviews on most major sites and provided through most major businesses, are lacking in proper moderation/review and bought reviews and shady reviews are definitely a major issue in these areas. I'd hate to visit somewhere that was ranked 4-5 stars on the reviews.. just to find out it's a trashy, horrible experience. There's definitely potential for a lot of market-grab when it comes to that!
Great post, thanks for sharing! :)
