Well okay but he said "message encryption"; everyone is reading into that to mean authentication as well but I don't know why we should extend that understanding when a plain reading of his post implies a harsher critique of PGP encryption than warranted. It's also amusing how many people downvoted me for disagreeing with tptacek.
