Yeah, I don't agree with this blog post at all.
Color highlighting in code is fundamentally different than in standard text. In text, it means, "I'm important!" But in code, the purpose is to categorize. When I read code, this is important because everything is in a category and in a hierarchy. So I'll skim through all the things of one category until I find the block I'm looking for, then skim that block to find the next category of code.
And the they have other points like, "if you can't recite all the colors and what they mean, then I'm right." No you aren't? Within ten seconds of looking at some code in some editor, my brain creates the color/category mapping, and then I'm good for the whole time I'm working. Why would I memorize it?
The whole thing just reads like someone had an epiphany and is trying really hard to justify it.
