This was flagged by users. On the other hand, the article is clearly substantive. As an experiment, I'm going to provisionally turn off the flags. The thread hasn't degenerated into a flamewar so far; let's see if we can keep it that way.
All: please take extra care to make your comments high in substance and civility, and as low as possible in flammability.
