When the first line of your article contains an Amazon referral link to buy the book and make you a quick buck, how is anybody expected to take your subsequent glowing praise of the book's contents seriously? Ending the post with a quick disclaimer doesn't mitigate this loss of credibility.

Using that logic, how could you possibly take the book itself seriously, since the publisher isn't just giving it away for free?
