I did read that article when Anil first posted it and while I agree with him, it's tough to apply his lessons on a day-to-day basis. You might come across several articles per day, and on each one you have to decide what you want to do about the comments. You could use the opportunity to launch into Anil's manifesto, but most of the time you won't have the time or mental energy for that, and so just leaving without reading the comments is the only real option.

Edit: On further reflection, I guess Anil was writing as much or more about the "Don't read the comments" joke itself as about what to do when you come upon a comments section. And in that vein, it's true that my comment is pretty unhelpful. I've deleted it.
