More than its 20 billionth tweet, Twitter should be proud that it has attracted a user particularly impervious to external suggestion: North Korea. The government’s Twitter feed (@uriminzok) went live last week, a month after its YouTube channel, and both have featured ceaseless propaganda—in Korean. The futility of these moves is unmistakable. The feeds are largely understood only by people in South Korea—who will disbelieve them—and in North Korea, where there are very few personal computers and no broadband Internet. A newspaper is said to be a nation talking to itself; North Korea’s Twitter feed is a nation talking to nobody at all.
