What's the deal with your nickname? How did you get it? If your nickname is self-explanatory, then tell everyone when you first started using the internet, and what was the first thing that made you say "wow, this isn't just a place for freaks after all?" Was it a website? Was it an email from a long-lost friend? Go on, spill it.
I was trying to think of a name for my (yet to exist) band. "Overglow" was one of the ones I came up with, but I decided that it was too pretentious a name for a band. It's just pretentious enough for Metafilter though. ;)
