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.

Make the important interesting.
