A resurrection of the previous most controversial discussion topic on this list. Personally I don't have a problem with it if women want a women-only place to discuss gender gap issues (although there are some immediate challenges: (1) this is the Internet, and (2) some might argue that male/female is an incomplete gender spectrum). On the other hand... In order to effect change and be more than an echo chamber, you might need the other 91% of us.
