I generally steer far away from posting about gender issues in gaming. The majority of these discussions have nothing to do with incentive structures, and it's very easy to talk for a long time (offending multiple people on all sides) without really getting anywhere.
That said, Anjin Anhut posted some intriguing thoughts on incentives in marketing. It probably isn't all gospel truth and it doesn't necessarily get us closer to solving the many issues out there. Still, the post presents a cogent argument for why financial incentives may be driving a long-running trend towards alienating a large potential segment of the market that otherwise doesn't seem to make sense.
