So one night, I was trying to set up some online account or another, when for the first time I found that the username I usually use was taken! I racked my brain to find something to try. I tried some old nicknames, all were taken, unsurprising since they were not unusual. Finally I tried KZ, and it was too short. That was different, so I thoughtfully pursued this line of inquiry by extending it. I happened to be watching Natural Born Killers at the time, and KZ is the name of my most schizophrenic ‘alter ego’. I found it appropriate, and KZisNBK was born!
