Well, in the simplest sense what's up with that is that it's reflective of the demographics that read OB. Which doesn't answer the real question, of course.

There was, in fact, some related discussion on OB at one point, I seem to recall; if memory serves me it mostly turned into some academic feminist types complaining at Robin, which seemed unfortunately unenlightening all around.

The two people in my circle of friends who I think might be most interested in this sort of thing are both women, but the quality of posts and comments here is still spotty enough that I haven't felt in a position to urge them to start reading. That may change as the software improves and we get better at getting the best out of this community; at the moment I'm hoping that your book when it comes out is something I could recommend.
