Like we say in the fraud biz - follow the money. Your bloggers are being paid for referrals so they cannot be assumed to be unbiased at face value. Do your homework before you jump on a blogger listed offer. That said, the bloggers for the most part are reputable folks and provide alot of information that is valuable to many, whether new information or aggregated information from other sources. Unlike the travel columnist of the newspapers of old, they are not salarymen (or salarywomen).
