I'd like to pick apart this post as a piece of really brilliant marketing. It gets so many things right:<p>* Link to a review<p>* Reviewer puts book in context of things I've already read. Gains trust.<p>* Incentive to evangelize -- the product is like this awesome book I've read, but easier to read. Everyone should read that awesome book, but it's too hard. Maybe I can convince them to read this.<p>* HN is the absolute perfect, laser-focused market for this. By definition, I want to read this book.<p>* The pricing sheet looks like a 37signals page--it's comforting and familiar<p>* DRM-free instant delivery.<p>This is actually the fastest (other than maybe at a grocery store) I have ever made a purchasing decision. It was under 60 seconds.<p>Damn, I wish I had marketing skills like this.
