focusing on reality- Female leadership

I have worked in development work with women for fourteen years and something really seems to be not right about priorities. I have seen a lot of women rise to positions of leadership and I still do not see the difference between female and male leadership. This makes me wonder whether female leadership will ever make any difference to ordinary women's lives or if its going to be about statistics without impact. I have seen a lot of the women turn out like the men they replace. I am concerned about what the women want in the leadership sphere is it just to replace the male figure and actually work in the same way that men work or is it to occupy the space of leadership and come up with feminine leadership which should be different. My question is as women what hinders us from coming up with a totally new construct of leadership different from male leadership? I am wondering if we cannot come up with a totally different kind of leadership that has feminine characteristics and test the impact it would have. I know the feminist leadership has been tossed into the leadership arena but I wonder why it has not been grabbed by the female leaders. I would really like us to share our experience of female leadership so we can pick up the best practices. I am waiting to hear from you
