I think that, despite making some mistakes of its own, the content of the article is still valid and raises some important points. I did find it irritating that they used small, light coloured text on a dark background in places, as I find this very difficult to read (and am hardly alone in that). However, I think there are bigger fish to fry than quibbles like that. On any given day, there's at least one article on the HN front page that I actually cannot easily read, and frequently it's black text on a white background, plenty of contrast, just far far too thin on my display. I suspect the significant difference between font weights in browsers between OS X and everything else may be to blame.
