I got mine from my resumé. Really, I did!
In a world dominated by "web masters", "web wizards", "web warriors", and "web ninjas", it seemed like a good idea at the time. "Fiend" properly illustrates the unhealthy addiction (think "crack fiend"), and isn't quite as macho as everybody else's. Plus, it provides an easy screening. The companies I don't want to work for are just going to throw away my resumé rather than talk to a fiend ;-)
