Not a comment on the article as such, but a pet peeve about the way it is displayed. There is a "floating" header on top which covers the text. If one hits the space bar to scroll a full screen worth, some unread text is covered up by that header. The same would be the case for the footer but, that one at least, can be collapsed. This is not the only site guilty of this (in fact it seems to be a growing trend) and I am surprised that no more people comment negatively about this.
