I'm actually kind of soft-hearted for the geek type. Not the socially dysfunctional ultra-nerd type, but rather the people who have an area of expertise that matches their area of passion.
Like my SO is an electrical engineer who'll happily talk anybody's ear off about the weird stuff he makes for fun and profit at home. I don't understand more than about one word in four when he goes off on it, but his obvious happiness and passion for something unconventional is just a source of joy for me.
In the past I've had that kind of relationship with a people who were that way about specifically motorcycles, quilting, computers, etc.
