I like to think that my written work falls under this genre, as it encompasses a wide deal of tropes and themes! Transformation is but one of 'em.

I wonder, would malleable characters be considered postfurry? I personally think they are. =P

As someone whose experiences in fandom have been ever evolving, I do believe in postfurryism as an art form!

Shame it seems oddly scarce here tho.
