Ahh, ....I'm totally uncreative.
Actually, I decided based on consistancy (plus I'm lazy). If I made up a new name for each ID, forum, webpage, log-in, and identity, I'd never remember them all. They all have different uses (work, jobsearch, banking, personal ID, recreation, etc.) so something funky wouldn't work across the board for all.
Plus all of the names I thought up sounded funny at teh time, but kinda tacky after a year or so. Coming up with new ones each year goes back to #1 above.

P.S. I DO enjoy everyone else's creativity, though. Some names and sigs are really good.
