What comes to my mind is a fumbling art student who's been called out on a bad piece, so he's now claiming it's a parody of bad work, or, no wait, actually the reaction of everyone to the poor piece is the piece.
He trots out the persona argument all the time, but I won't give it to him. A persona isn't a set of fake glasses, nose and mustache you can wear whenever you don't want something attached to people's image of you. People with personas make a great effort to separate them from their real selves – wearing costumes, using different names, and actually behaving differently. Ranting from zedshaw.com under the name Zed Shaw doesn't fit my idea of a persona.
Also, it bothers me that the supposed real Zed Shaw uses this deletion to criticize people and put them down (for taking his "persona" seriously) – something his "persona" was well known for.
