It has to have been better than Kaila1996.
In my initial forays into America Online, I was hardly brilliant, in the screen-name creativity department. The worst part is that I kept updating the name, until "Kaila1999" stuck, and saw me through college. When I first joined Gawker Media a million years ago, everyone still used AIM to communicate, and "Kaila1999" was on my first business card. "Do you really like Prince?" someone once asked over chat. I wish it had that cool of a origin story.
Do you remember the first screen name you created, and why you chose to give yourself that moniker? Bonus points for the year of signup.
