All I see is "Look how cool and special I am! I'm a girl and I can navigate in the men's world!". She tries to bring up a problem but I cannot quiet see a real problem there.
"Already at a disadvantage, they are playing a seemingly impossible game of catchup with very little positive feedback or support. The culture, the standards, and the norms are all male-centric, and the book talks about women in computing being guests in a male-hosted world."
It's a big problem if you want to become an average programmer that has to rely on that feedback and support. Guess what? Most truly skilled people learned almost everything by themselves. Generally speaking most intelligent people learn by themselves (if there are means to do it) and find themselves a little alienated from the general culture.
My point is simply if you want to achieve exceptional results you will most likely be an exceptional person too. And being a woman, being ugly being whatever will not have much influence. In some situations it will help, in some it might do the opposite, it's random.
If you want to be average then yea, as a woman it will be harder in IT, but if you want to be average why not pick a job average woman does?
