Some automated app gimic scans your tweets and then tells you when you typically sleep. It also assumes that when you sleep you don't tweet. I assume that's a fair assumption in 2010, but I doubt such for 2015. Anyway, of course it also presupposes that when you are awake you are tweeting. Quite a premise, no doubt self-serving.

One reason, perhaps, is that the remembered emotion was instantly buried under a pile of cultural junk.' - Tod Gitlin in his review of Susan Faludi's The Terror Dream (written for
