This guy has such an ego problem. I'd hope that the PSF would actively ask people to stop linking to learn python the hard way, when it's teaching a version of the language that's over ten years old (and it's far from the only resource). The book has the benefit of having a catchy name that people can easily recommend, but that's about it. This guy really needs to get off his high horse, I'm even considering writing my own book just to compete with him.
