I am not surprised at all a study found that less women say they "love" programming. In my career I have worked with many women, and none of them would I consider less than well-rounded as a person. But I have met many, many males who are heavily skewed toward the "hacking is life" mindset. Nevertheless, the two best programmers I have ever known are women, and they did not identify as "hackers."

Hacking is a culture, not a job description, and in my experience, singleminded dedication to programming is not an indicator of ability. So I guess the real problem with "Hacker School" is that it's a programming school not a hacker school. A hacker (programming) school could never say anything like "you don't have to love programming" because being a hacker is pretty much defined by loving it.
