I'm actually having a hard time deciding between several solid contenders (and their totally-not-their-alts alts) but I'll go with one that I had very little actual interaction with: the "cranking the hog in front of coworkers whether they want to see that or not is liberating and if you're against it you're a reactionary scold" Whedonbrain we had that one time. :volcel-judge:
I'm with you, but I think everyone agreed that "Beatnik" as an identity needed to die, and there guy behind the account can either start over from scratch or move on. I've always wondered if we'd hear about him again directly or via a mod, but probably not.
