In March, the Women Power and Politics exhibition asked if you think having women in power makes a difference. We deliberately used "women" in plural because, for the first time in history, we are seeing women exercise their power as a critical mass, be in formal politics in the Parliament of Norway or the village councils of India or in more informal ways, as religious leaders in Morocco, community activists in Nigeria or grassroots leaders in Mexico. What do you think are going to be the effects of this critical mass?
