I received a solicitation to place a good comment about a book on Amazon.com because I had given kudos to some other books. The author offered me a copy of the book. I think that this is a pretty normal practice in print too. However, I do wonder how many reviews/comments are paid and not just a grassroots response to a product or service. I find this to be especially problematic when trying to find out whether a web host is any good.
