I think it can be phrased more nicely (without satire), but the general message seems to be useful to novice web designers: to avoid overcomplicating things, to pay attention to accessibility, avoid breaking it too badly. Especially since many books/websites/guides will describe fashionable techniques without paying attention to that.

I'd also suggest reading Principles of Design [0] and other Design Issues [1] by TimBL, WCAG [2].
