That's a good point. I do think that when advice is very detailed and specific, it's more likely to be accurate. When people are fooling themselves, or trying to fool their audience, with this kind of thing, they usually speak in generalities. It's too much mental hard work to make up something very specific, like "You should use vim or something like it", followed by detailed reasons why that's a good idea; that, to me, has the ring of something Doctorow has thought about a good deal. I'm _not_, of course, speaking of 'specifics' like the "20 minute" number he talks about; it's a detail, sure, but one that is very easy to make up.
