Usernames: Thoughts

[astoryandasong]

So I have been thinking for a while about changing my username, and I just kind of had a comment that made me think: Gemma, your username, while being cute six years ago, has become uncute. For real. It wasn't a bad comment or anything, not at all, I totally agreed with it. Highlander Fandom----> Panic! fandom? Do not go. In fact my username limits me, pretty much even in my own head. Therefore, I am thinking of changing.
Something non-fandom specific. I'm Flame_alchemist on buzznet and myspace, but again I don't want to be that.  So here is a question, how did y'all pick your usernames?
