Code of conduct: If people can't play nice by themselves a code of conduct wont help. There are a few not very friendly people even moderators currently active in the wp.org forum at the moment I can't see them being friendly just because there is a code of conduct. Will unfriendly but higher ups be kicked out if they break the rules?
Personally I go by the age old "treat others as you want to be treated yourself". Don't think anyone wants to be called stupid.

Feminism The whole women thing is ridiculous. If women want to code wordpress let them. No need really to try to get more of them. Not everything needs to be a 50/50 project. Personally I'm kind of sick of such projects really. They are mostly political in nature. Never do you here "We need to get more female garbagemen or dishwashers".

Core The core stuff is just bad.
improve wp.org More social tools etc on wp.org is welcomed and a great improvement perhaps.
