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.
For a while I was writing a fictional blog that I tried to pass off as reality, about a man traveling back and forth across the US. The situations were false, and so was he, but a lot of his sentiment and desires were mine, usually the kind I couldn't express in day to day life. I started to consider him my alter ego. Half the name is his, half is mine.
