Paul Graham is a good writer, but many of his essays annoy me because they assume his experience is the only valid way to program. That's why I loved it when Maciej Ceglowski (who can both paint and program) called him on his Hackers and Painters essay.
I am not qualified to call bullshit on Paul Graham when he writes about programming, history, starting a business, or even growing up as a social pariah, but I do know enough about art to see when someone is just making shit up.
