We all know men and women are different, physically, psychologically, etc....so allow me to offer my viewpoint (these are gross generalizations, but I think you'll get the point)
Women act more based on emotions and feelings than guys do, whereas guys will act on logic and black & white facts. That's why you see more guys in fields like physics and mathematics, and more women in things like psychology, education, etc. (it's also why guys are more sports-inclined and women prefer yapping about everything and nothing over coffee)
Based on this, I think it's perfectly natural to point out that computers fields (very fact- and logic-oriented) are dominated by guys....
Flame this if you have something meaningful to say, I love debates on male/female dynamics & differences....
