Since this is no longer about my comment, but rather about me, let me open my response by saying that what I really don't get is what drove you to consider my uniniteresting comment worthy of your time and words, instead of simply downvoting it, just as many people did (some upvoted, though!).
Merely raising a point isn't really enough - there has to be a reason to raise it.
My point, in case it was not clear, is that there is merit and elegance to not using CSS at all. It is (arguably!) the purest way of exalting content: forgetting completely about presentational aspects. My point, maybe not well explained first, is that it is noteworthy to see this kind of choice in 2011 by a tech-savvy author. It may not be interesting to you, but it is for more than one person. See, e.g., [1], [2].
I accept this may not be interesting to you, and even to most HNers. Rest assured that if (and only if) I find an overwhelming proof of the latter, I will avoid this kind of comment in the future. But, for the love of Ken, don't even try to take ownership of as subjective a concept as "interesting". Heck, an article on anything at all on HN brings up well-received comments on ping times, DNS servers, JS file delivery, etc. and, um, that may have nothing to do with the content of the article itself. That's one of the main reasons I, for one, love HN.
