I think the author does a great job starting out by highlighting her own contributions via the linked write-up on Git submodules, but beyond the first couple of sentences on the topic nothing, and spends the rest of the article on a tear about the he/she dichotomy in comments.
While I can certainly understand the frustration when people get gender wrong, that seems to be the wrong place to focus on in this topic of women in tech. Is it possibly an indicator of the problem at large? Sure. Does it answer the question "Where are the tech articles written by women"? No.
It does play right into the exact same mold the commenter was talking about, that set this entire entry into motion:
There are plenty of contributions complaining about oppression...where are the technical contributions?
Instead of highlighting great articles from the women in tech, or linking to other women in the industry with well trafficked blogs and talking about their contributions, the author fell right into the category that perpetuates this problem.
Mind you, I agree that there is a rift that rises when people make the wrong assumption, but that's nil imo.
