Not a lot. A lot of people call me Q, including several RL friends. That got started and just sort of stuck. One chick used to call me Monkey (because I often go by Mikey, and I had a lot of monkey crap people used to give me... stuffed animals and wind-up king kongs, whatever), but she didn't use it too much. So... mostly just Q. Which I respond to probably more quickly than my own name, since half the people who call me by my real name are people I can't stand, when almost everyone who calls me Q is in my good books.
