When Do They Sleep? (On Twitter)

While we’re certain that if the When Do They Sleep? algorithm were to actually be applied to some of our friends, it would surely snap in two out of frustration, it’s still an amusing toy. The concept is to enter a Twitter username into the form, and SleepingTime coughs up a rough estimate of when it thinks said user is “sleeping” or is most predictably inactive on Twitter. Three sample lists give us snapshots, and “Tech Superstars” is a bit bizarre in selection if not interesting to browse and imagine that some of our friends actually ever sleep.
