Yeah, the Pixies definitely do rock. I was pretty happy to see a thread like this actually come up I've always been a little curious myself as to a few certain peoples' nicks, and their meanings, or reasons for choosing them.
Digipravity is more or less the nick I've always used. It basically means 'Digital Depravity'. My reasons for choosing it are kinda obscure and hard to explain, hehe. Part romanticism, part social commentary, part humour, part nihilism, part blah blah, the list goes on.
