Can you elaborate?
* facebook got criticism for not hiring enough women as coders.
* facebook hired more women (probably lots of junior coders)
* they do what junior coders do
* someone turned the code review rejections into a spreadsheet and disregarded seniority (experience mainly), and made the issue about gender.
Or, to put it another way: when contributors are anonymous and genderless, work by women is accepted at the same rate as men?
