Your approach to the whole thing was very much affiliate/internet marketing oriented: list building via PPC, squeeze page, product sold through ClickBank, generous kickbacks to affiliates, high price for low page count, artificial urgency created through a limited time offer, and so on.
Here is what I admire:
* You managed to do all this without pissing off geeks, who are very sensitive to bullshit and tend to have an holier than thou attitude towards these techniques.
* I didn't buy the book, but I suspect it's rather high quality, compared to most junk sold on ClickBank.
* Your landing/squeeze page is surprisingly classy. It manages to accomplish a good CRT, despite the lack of autoplaying audio/video, exit popups, and the typical centered column look.
In short, good job.
