Apparently there are too many geek guys and not enough GirlGeeks. Some people have tried to reconcile this unfortunate situation with Geeks and Girls Humour. However, a SlashDot post refered to a study that claimed Girls Don't Want To Be Geeks!
"According to a study by the American Association of University Women, 'Girls have the ability to learn and use computers, but they are turned off by technical careers that they view as full of geeky guys'. The study blames the general sentiment on a gender imbalance in access to computers, and on social pressures that steer girls away from technology."
