Another friend in high school, whose name is also Tom, went by the nickname "Mot." Maybe he was dyslexic or something, I don't know, lol. He started calling me Mot, too, and it stuck. I, in turn, called another Tom Mot and it became briefly fashionable to be called Mot if your name was Tom. Fast forward to the internet and the era of usernames. For a while, a username like "Mot" worked just fine, but eventually 3 character usernames fell out of favor. Long about that time I was starting my internet radio station (Girls Rock Radio) and adding "dj" to the beginning seemed a way to connect another part of my professional life to my online persona. But I keep the "dj" part lower case as being a radio Disk Jockey really isn't a formal skill for me (even though GRR is the premier destination for the music of women artists in the rock, pop, and alternative music genres on the internet today,) so being lowercase is my way of de-emphasizing that skill. Plus, it kind of looks cooler with the mixed caps. Unfortunately, 5 characters is still too short in many situations, so I sometimes have to add other stupid shit on the back end to pad it out. That's my story.
