I found his “Resolving the Gender Gap” paragraph quite credible. Heck, it's even a viable description of some HN comment threads.

I'd very much appreciate the input of women on this, but alas, they are few and far between in our profession. If the author is actually wrong, they might even be too busy being “good developers” to show the same amount of “disrespect” for the field as he does. But I'm not prepared to believe that yet.
