I just looked at this guy's startup. How the heck is it making money? Are people really so clueless as to not know that the same information can be had for free from dozens of websites just a Google search away?

There isn't even a free trial! How can they expect people to pay $50 up front on the strength of their nonexistent brand name?

I am seriously confused. The only explanation I can think of is that they get all of their traffic from this guy's blog posts, from HN hacker wannabes who want to learn to code and didn't think to Google.
