I'm afraid you've gone and gotten about 3 levels way too esoteric and fuzzy-navel-philosophy for me to see the appeal tbh.

If you're trying to hash something out between yourself and yourself, the only reason to do it in front of an audience is for attention. To be honest the exercise, if conducted in a 'public' space, would seem mastubatory to me if I knew what was going on. And if I didn't know, it would really be an exercise in deceit, not an exercise in self-dialogue.

If, on the other hand, you are trying to have an anonymous conversation with a bunch of other people, I think it behooves all involved to present your multifaceted, complex, or inconsistent ideas/thoughts/etc as cohesively deriving from whichever single mind spawned them. It's easier to understand where the parts came from if we are shown they belong to a whole. It also helps remind everyone that we're all human, and we're all multifaceted, not absolutionist caricatures only capable of black-and-white opinions.

Those're my opinions. If a permanent throwaway was created, I wouldn't use it, but that doesn't mean I'd petition others against it either. I just see far more potential for drama and harm than benefit.

I hate hubski drama.
