I also think, no offense, that HN is a terrible, terrible market to sell to. Among many other signs: if the price point a hypothetical customer goes to for "Actionable advice which stands to make my business a lot of money" is "thirty bucks", I have negative a billion desire to be in a business relationship with them. No offense intended to anybody here. Instead of spending six weeks writing and then a year wheedling people to part with their $50 as if that were a meaningful amount of money, I could pick up a phone tomorrow morning, call one of a couple CEOs, and say "So, still want my help?", and then do six weeks of consulting. There would be very little wheedling over $50 involved.
