I think the reason we don't see women developers is that women don't have a long term obsession over something which is required to complete a major roguelike or some other large scale project. Women seem to always try everything that men do, just to see what it's all about and then they move on in their life to next random thing. That's why you can never trust them. Also I have always thought that women are simply less creative than men, the reason why everything ever was invented by men. Well except that dish dryer shelf, it was invented by a finnish woman.
