What's up with "coöperate" always being spelled like that!? It's driving me nuts every time I see it in this damn book!! Umlaut, diaeresis, I DON'T CARE, it shouldn't be in a book published in 2014! I'm sure New Yorker had some stupid style rules back in the 50s & 60s. But it's ridiculous that wasn't edited out for the 2014 edition. It just comes across as pretentious, unnecessary and DISTRACTING as hell.
