I'd want them to be conservative, but not closed to new ideas or afraid to try out better ways of doing things. Little to no drinking and preferably no smoking (at least not indoors or around me if it can be helped). A mind for common sense, logic, technology, and programming concepts. Skinny or medium build (aka not fat). A geeky/awkward look. Mostly introverted.
The most interesting thing to all that is that I've pretty much described myself. Yes, I'd like to associate with a variant of myself.
