I'm getting really tired of such sexism-rerated blurbs. I'm tired of hearing and reading about some people's ideas about how to force an increase in the number of women in politics, in academia, wherever. I'm tired of these ideas mostly because most of them feel themselves forced, and very often drop over to the other side of overly positive discrimination horse. I'm tired of them, because most of them don't contribute and are worthless, or simply disregard the real world, trying to envision some half-assed gender-neutral utopia. All stupid crap.
I've spent now more than a decade in academia, and I've always had women colleagues, during msc, during phd, after phd. Not many, naturally (fairly typical CS/IT ratios), and even today from the 9 senior (young postdocs and "older" postdocs) in our lab onyl 2 are women - which I think is a fairly average ratio in our field. None of my earlier or current female colleaues/coworkers had such negative experiences as the blog post is about. That doesn't mean others didn't, but sometimes I have the feeling such stories are a bit overreacting and over-generalizing.
Personally, I wouldn't mind to see more women in scientific fields, but I couldn't care less if there weren't any either. I just never thought about such numbers as ratios as being an issue. It certainly never occurred to me - or anyone I've ever spoke about such topics - that women couldn't perform in our field, since I know from experience that they can, furthermore, most women I know - personally or because of their results and publications - in our field are really exceptional in their areas, very many of them are much better than me or some of my colleagues :)) And the ones I do know personally always seemed to be really motivated, since they want to show they can do more and better. Which, while is nice, it's really unnecessary, nobody I know would think they are inferior. Also, performance&results are important, gender is not.
So, tl;dr, sexism and gender issues: don't care.
