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 used to blog about crime under the name Bookhouse Boy, both a Twin Peaks reference and because I write in a room filled with bookshelves. I dropped the "boy" section when joining Metafilter, as I didn't want to come off as a deranged Lynch fanboy.
