The thing is, I've been around HN for a few years. I've seen people like patio11 transform from what they were doing before, to selling these types of courses. I've also seen patio11 give out free, amazing material for the last 2 years. And a lot more before I was around. So when someone new to the "scene" is skeptical, I find it very funny. You have a right to be skeptical, of course, but really the best most of us can offer is to say: "These people know what they're talking about. And they're not just selling snake oil. We've known them for years". Maybe if enough people say it, it will help prove to you that it's not just a "marketing scheme". P.S. I don't know Brennan Dunn, and haven't (yet) read his book, but he is endorsed by patio11. So is Amy Hoy, if I'm not mistaken. And with Amy, I've also used her time-tracking software for some time.
