I'd like to ask you to think twice before publicly questioning someone's credentials like this. Whatever your intentions, picking on someone's CV just because of a blog post you disagree with is not only rude, but it sends a message -- particularly to women in tech -- that if they speak publicly, if they offer up their opinion, they will be attacked not about the content of their point but about their competence to speak at all. I believe this kind of attack has real consequences on our field, and I would urge everyone to show everyone the respect they'd want for themselves.
