Shocking! (Context.) A shame he didn't understand the paper, though (alternatively, if he did understand it, a shame he couldn't make any relevant counter-arguments). Do read the first few comments on the post, they're very funny.
(Kudos, by the way, to Justin Tosi and Brandon Warmke, who instead of demanding a juvenile pity-fest for their vulnerability, communicated to their critic that given that the paper was in the public domain, it was fair game for mocking criticism.)
(Thanks to several readers who brought this to my attention.)
