John "Urbie" Kafalas, tech writer, editor, journalist, musician (trombone, tuba, and other low brass) and recent business-school grad. Like most people, I use Wikipedia a lot -- but I only edit articles occasionally and have only authored one original article. I'm not a self-appointed WikiGnome or other such creature -- but where I see a factual error, I correct it.
For more info, see my web site, which is, obviously, kafalas.com!
