I found the female pronoun use, including the "separate the women from the girls" line, to be delightfully distracting. In a perfect world, I'd say pick a singular gender and go with it for the sake of consistent grammar. However, from my experience, women still deal with unfair perceptions in the work place. This is an easy, subtle way to combat that. I think it's completely worth the distraction. (Note, many writers have done this for the past few years, not just Ben, but it really stands out in the context of a tech startup CEO).
