Drunken rant? He comes off as much more reasonable than Yegge. Which part is the drunken rant? I only skimmed the religious part because it doesn't interest me, but I have read much worse than this from both religious types and software prima donnas. This is mild.
OK, so he says stuff about his religious views. Not my cup of tea either but he doesn't come off as a jerk about it. And it's fair, IMO, for someone to say their religious views influence their work. That is up to them, their personal opinion. Just because I am not religious myself doesn't mean I have to trash him about it. (Hint: When he says he hears from God, I don't think that's literal.)
I'm wondering if both you and Yegge are misrecognizing some of his sarcasm? (I guess Yegge is probably also exaggerating the personal aspect for comedic effect.)
