I picked this nickname back in the early AOL days, when the conventional wisdom was to always obscure one's real identity. It became a habit I have never bothered to break. I sign most of my posts with my given name as a nod to today's less anonymous community norms. But putting out my full name is more than I can force myself to do. Like writing in books or pulling a push broom, it's just been inculcated into me as something one doesn't do.
