I think people are too harsh with the author. He is clearly in the beginning of his hacker path. I think everybody who disagrees here can remember a time, when he thought the same way. The author here got a basic idea very correct: You want your code to be readable. And he still has to learn, that good code itself can be (and often is) the most readable way to express a problem and its solution. Often there just is no better way to express, what the coder wants to say.
For everything we code we have to keep in mind that every line we write must have a meaning. That is true for code as much as for documentation. If the problem is complex and the code is hard to grasp, but it is well written, then probably every line of documentation you write will degrade the readability and also end up beeing a waste of the time for its author and its reader.
I don't think people are being too harsh. He put his opinions out there in a very proscriptive way. He didn't invite discussion, he merely dictated his opinions. And he is quite wrong.
Additionally, his blog is called ProgFu. That gives the impression that he is highly skilled and experienced; an authority to be heeded, like the sensei of a dojo. But if you look at his writings in total you can see that he's pretty green. His factual pieces are really useful, the opinion pieces less so.
While I'm thinking about it: I'm dismayed by this trend of bloggers dispensing programming advice like they are Miyamoto Musashi himself (although he would never display such hubris). Exchange of information is what's important. If you have a personal experience, share it, and perhaps discuss the lessons you've learned. But, please, don't write articles merely stating your opinions without backing them up with some evidence or experience.
