Sales info on bjfonline.com
I was one of the BJFO moderators who sometimes mentioned books for sale on the site, so I want to comment on that point.
On the Usenet newsgroup rec.gambling.blackjack, where nothing is for sale, I sometimes answer newbies' questions by pointing them to a book. The simple fact is that, in a few decades' worth of existing blackjack literature, you can find answers to quite a few questions. On RGB I've also given information about where such books can be purchased, including links to bj21.com, ConJelCo.com, and rge21.com.
On BJFO, a site hosted at no charge by Huntington Press, it just seemed tacky to me to refer people to one of HP's competitors. Therefore, when I recommended a book, even if it was a book not published by HP (such as Blackjack Attack, published by RGE), I gave a link to where HP was selling it.
There was no policy on BJFO of trying to increase HP's sales. The moderators were never instructed to hawk HP products, to avoid criticizing books published by HP, or anything else. When I referred to a book, I did so because I thought my comments would help people find their way through the many blackjack books available.
The only time I can remember that HP's commercial interests were involved was when someone posted something about how to abuse Las Vegas Advisor coupons. Anthony Curtis responded, with some asperity, pointing out how the suggested tactics would make the casinos less likely to provide the coupons, and thus be harmful to the players overall (as well as harmful to HP).
