How many of you guys use fake names? Why do you or why don't you use them? How did you choose yours? In general, what's up with your alias?I use Inertia because I want privacy. Every name in my zine is an alias and some of them are more fitting than their actual name. For example, I call my tiny, passive, darling little sister Mouse.
