I have a hunch that part of this is related to the fact that nerdess is German. Or at least, she's based in Germany per the site.
I'm from Denmark (and a guy), and I can say from firsthand experience that attitudes towards women in Europe are still very old-school. Not everywhere, certainly, and Europeans are open-minded liberal socialists etc, but behind the scenes the old attitude of "women and technology don't mix" is very much alive.
For example, many guys in Europe I've spoken to will make jokes about girls not really being fit to work on cars, working with computers, or doing anything "technically hard".
Even some years ago, there was an advertising campaign for a lotto (or something similar) with the tagline "so simple even a woman could understand it". The advertisement featured a pretty blond woman standing in her kitchen, listening to the boys hoot and holler about their winnings next door with a vacant expression on her face. This was plastered all over the main train station in Copenhagen.
So, while I agree it probably seems like an alternate reality in the US (assuming that's where you're from), it's not so far-fetched in other parts of the world. Just my $0.02.
