When most women break through glass ceilings for the first time, they do it by playing the rules of that industry-- ie, behaving like a man. Compare and contrast even the last generation of tech leaders, Meg Whitman, Carly Fiorina with the Sheryl Sandbergs and Marissa Mayers of today. The former would never dress as feminine as Sandberg or Mayer, nor would they openly talk about their children and the plight of women in tech. They couldn’t.
I also wholeheartedly recommend the Ezra Klein piece linked. Not sure if it's been up here before.
