Oh come on, geeks aren't that hard to figure out; men, maybe. Girls? Definitely. But you don't need a manual to figure out a geek, do you? If you do, here's A Girl's Guide to Dating a Geek ($14), which offers, with its tongue in cheek, how one should go about dating a geek.
I've already told you where to find fellow geeks, and now if you need help in the actual dating of the geek, here it is, I guess.
P.S. Where's the guy's guide for dating a girl geek? They're the ones who need the manuals, in my humble opinion.
