pg, whatever you read into this rant, please don't let it make you go soft and pull your punches in essays, posts, talks or interviews. Most of your audience prefer your straight talk to mealy mouthed, watered down, PC blandspeak, even when you're wrong. And if destitution necessitated scurvy (out of all things......) turns out to be a huge problem amongst your founders, I suspect there are investors out there willing to come to the rescue, even at twice YC's valuations. No questions asked :).
PS: for those who find the IQ test comment arrogant; Paul Graham is just showing off his mastery of Cambridgeian lingo. Back there, saying someone has low IQ is short for saying they disagree with you. Nothing more, nothing less, and absolutely nothing to be all up in arms about.
