My parents signed us up for AOL's first dial-up service when I was twelve. Since then, I've managed to hold onto my first screen name (a reference to my then-favorite band which is too embarrassing to share here), even though I don't use it.
In college, my friends and I laughed over our screen names, chosen as adolescents but too close to our hearts to give up. I eventually switched to a work-friendly AIM account name, but a few times a year I'll sign online with my screen name of yore.
Plenty of my friends have original names, most featuring band or celeb names, often with a lot of Xxs or other characters for design effect, and always good for a giggle. Have you held onto yours? Brave enough to share it?
