Fair enough. I think it's relevant to HN because when the hacking is over, sometimes it's necessary to make money From what you built. There was a post recently where a guy built an awesome piece of software, but had almost no users. If he reads this article, that could change, and maybe from all the money he makes from users he could afford to hack on another great piece of software. So this article could enable people to hack more.
That's why I think it's relevant to HN. Why do you think it isn't?
