A whole lot of nope,name came from an amazing album from an amazing band and was my e-mail address for many years.That and I think the announcement "you were dismembered by chaosphere187" has a nice ring to it.
I still have no regrets on my name, it is original and memorable. I was a early adopter to the PS3 so there was no need for numbers and with all caps to make sure there were no other people making dummy accounts of it.
(They had tried and my friends spotted the phonies)
I like mine, it's unique and nobody understands it Sure people may think I'm a lagging forgeiner scrub (maybe) but doesn't matter. Most of time when people get mad in video games they start to suck. Well from my experience.
And yours "poodude" I'd hate that PSN, sorry!
