So I've been reading Eric Raymond's book. I'm finding it to be sententious, pretentious, contentious, badly elaborated, and generally sophomoric. (No offense to actual sophomores intended.)
It alludes more than explains, and that makes me think that its points are largely inaccessible to people who don't understand most of them already. That's always a bad sign.
I'm quite glad I'm just reading the online version and didn't do anything rash like pay for a paper version.
