Super cool. My name's kinda plain-jane, but I think it's a cool name. It's Matt if I didn't mention earlier.
I hardly use my real name or nicknames in my online usernames, though. Most often, I draw inspiration from things I enjoy, or try to be thoughtful and witty with usernames.
Mine range from Casinopolis_Is_Burning to Czarcasm, and of course, RazorCraft.
