I do this too. People frequently wonder what force of nature managed to turn an itinerant techie into a conversationalist, but the answer(s) aren't conducive to anyone's sanity so those aren't questions I elicit. I tend to think most people want nothing to do with my working as a hacker but I'm usually wrong so I overindulge their curiosity when I can because I might as well see if my knowledge & opinions make it all the way around the globe & hit the back of my head.
