Forget the geek girls, go for the geek women. That way you know this is not some college fad, but rather a long term personality attribute.
None of the people I was geeky with in high school (Trek, LOTR, D and D) have ANY interest at all in anything pop culture today. They had probably completely divested themselves of these pursuits long before they hit 30. They, as one person somewhat scathingly said to me, "grew up".
Watch out for that people, the ones that grow up.
