I don't do this because technically-inclined women are rare and I'm not attractive enough to cut off 95% of the possible partners out there. Or put more bluntly, you wouldn't pepper me with tons of questions at a party, you'd pepper my colleague M, who has a more outsider-visible job and is dashingly handsome. I have to make do with his leftovers, and I can't be picky about them having technical expertise.

Also, women who aren't fascinated by computer simply do not care enough to bother trying to explain things via metaphor. I have a friend who was asked at a party "What do you do?" He replied "I'm an engineer working on--" and before he finished his sentence, she stood up and walked away. FYI, he's the suavest person I know and is _extremely_ successful with women, usually: he's learned to stop trying to explain or even mention his job at all.

I recommend you don't try giving people advice on approaching women and what to say until you've _tried it_ for a few years, which as a presumably-straight women I doubt you've done.
