"Superficially ugly code is irrelevant. Pretty formatting--or lack thereof--has no bearing on whether the code works and is reliable, and that kind of mechanical fiddling is better left to an automated tool."

I disagree with this one. Clear, readable code is... clear and readable. It's like not bothering to format text in a textbook because "the meat of the matter is in there, so who cares?"

Of course substance is more important than style in programming, but style also helps and is it really that much effort to make sure your code is readable for the next guy who comes along?
