Developing women in the workplace, is it different from that of men at your workplace?

I found this very interesting TedTalk by Susan Colantuono, The Career Advice You Problably Didn't Get.  She states that women represent 50% of middle management, yet the number of women at the top of the organization is less than 1/3 of that number.  She shares her insight of why that could be...different approaches of professional development.  Check out the TedTalk and tell me how it reflects professional development in your workplace.
