The Olympic Games are for 'the youth of the world,' but they're organized and scored by countries. It's no surprise that countries treat them as vehicles of national pride, and assume that their people will be most interested in their own athletes. So anybody who was saving up to write an angry letter, blog post, or op-ed about NBC's chauvinistic coverage: don't bother! They're actually more above-the-fray than most. Also, their coverage is not shown anywhere except America - I know, it's because I can't get it that I'm watching Women's Air Pistol - so can't ruffle feathers elsewhere.

The worst kind of management seeks a single optimum, a one-scale index of efficiency, like the mindless scales of 1 to 10 for grading a woman's beauty or one to four stars for a movie's appeal.

Societies are healthiest when their radius of trust is broad and when people feel they can influence their own fate.
