Having been a member of online communities for about the past 20 years, I've constantly been forced to try and come up with any number of handles, e-mail addresses, nicknames, etc ... although I've been through a lot, most of my currents are "It's Just Rob" or some variation thereof ... I'd pretty much given up on anything else.
All my life, I have been consistently described as "cute". Although flattering in many ways, I'm sure that many can idenitfy with the sting that "cute" can sometimes bring when you're looking for "sexy" or "hot". One day shortly before Burning Man 2003, a "cute" vs. "sexy" moment prompted me to think to myself, "I *like* that I'm cute!" I decided then that that would be my playa name, as Burning Man is the time of year when I really feel the most in love with and unquestioning of the person I really am. The choice of spelling really has no other basis than c-u-t-e seeming a little boring ... although it often requires an extra step (note my signature) to explain that it's pronounced "cute" and not "cutie". Hey, I said I liked being Qt ... I didn't say it would be easy.
I have to admit that there was an unexpected, but very pleasing benefit. When I would introduce myself to people, I would say, "Hi, I'm Qt!" and I almost always got a smile followed by, "Yeah, you are!"
