The strategy you outline seems to have a bad reputation in Hacker News circles, though I'm not sure why; as long as the product in Step 1 is valuable by itself, the strategy certainly isn't a bait-and-switch. In any case, that's not what the Rails Tutorial Vanguard is about. I'm trying to keep the Vanguard small (say 5–10 people), and several slots have already been filled at an earlier price, so the Vanguard is not designed primarily as a money-making operation. (I've spent the equivalent of six months full-time on the book, so even a $5000 return would be a pittance compared to the opportunity cost.) Instead, the relatively high price is a way of attracting Vanguard members who place a high value on small-group and individual mentoring. People who don't find such attention valuable should wait for the release of the (much cheaper) screencast series itself.
