Yup -- lots of geeky guys, geeky/normal girls (Score 2, Informative)

I'm doing a PhD in computer science (major Linux kernel hacking), so I'm about the biggest geek you can find.

I started dancing (primarily vintage swing -- Lindy Hop & Balboa) at age 23 with zero experience, rhythm, coordination, or fitness. Since then, I've driven 15,000+ miles just to dance and met hundreds of people across the northeastern US.

Dancing is a great way to make a wide variety of friends in all sorts of geographic locations.

*** Plenty of women, from a variety of backgrounds

*** Plenty of fellow geek men (ie math or sciences). Something about the structured social interaction and dancing makes it attractive to us. It's much less intimidating than going out to a club. Dancing is easier with a partner -- the responsibility for performing is diffused & shared, and coordination is biomechanically easier with someone else to help you. At least initially, the dance patterns are standardized (though there are many layers of variations and subtle differences that can be introduced at a higher level). Also, in an evening of social dance, you're expected to dance with a whole bunch of diff people, so you're forced to meet new people :-)

Women that I meet while dancing are never surprised when I tell them that I'm in CS. There are at least four male PhD student dancers (ballroom and swing) who work in my hallway. This phenomena is pretty general: high dance penetration in many CS, physics, and math departments around the country. I get a kick whenever I see a swing DJ post on a Bugzilla for a Linux media app, or geek out on hardware/software on the forums.

Are you still in university? Great options.

*** Go to social dance club. They're usually pretty big, with plenty of n00bs. At my school, 90% of the active members are PhD students in math/science.

*** Go take the level one dance studio class (i.e. modern, ballet, hip hop). Gender ratio is in your favor for meeting women (about 10% guys, 90% girls). Plenty of awkward guys there, so you won't be too embarrassed. As one of the few guys in the class, you automatically stand out socially -- people will want to know why you're taking that class.
