I'm a geek in the "curiosity and technical aptitude" sense but not really in the "gaming and sci-fi" sense (and "oh my god you have to watch _____" is a huge turnoff, no matter what's in the blank). If you invite me to, I will talk your ear off about language and linguistics; I wanna hear about the thing you're equally excited about too, if you can explain it from the ground level.
I use this browser script to make the OKC header data queer / genderqueer / polyamorous-friendly, because I am those things. "Queer" for me means "all genders invited to apply," and "genderqueer" for me means "neither male- nor female-identifying." The poly part isn't necessarily set in stone; all else being equal, I'd prefer it, but all else is never equal.
