Or maybe schtick is the best way to put it. Or performance art. Or too much time on their hands (that's actually all of us 馃槀)
In other words, who's playing a character here and doing it the best?
My vote is for HipYoungDude. He never, ever gets out of character and is generally cranking out something everyday. Randy's a close second, but sometimes gets out of character. Ammoniascrubber would have won a few months ago, but seems more quiet recently. I have to be missing someone though...馃
