From the article: "his book has not garnered the sales for which he had hoped. In the days since its launch, he said, he had sold just one copy." From the Amazon product page: "Amazon Bestsellers Rank: #96 Paid in Kindle Store" The book already has 1,917 'customer reviews', but few (if any) of those reviewers have actually bought and read the book. I'm guessing that the 'bestsellers rank' isn't made up solely out of sales numbers but also of page views, reviews, user contributed artwork, and the like. That would mean that the criticasters are actually helping the book gain popularity.
