South Koreans are orderly. They obey laws, offer things with both hands, avoid eye contact, work hard, believe the number 4 is unlucky, and have small dogs. That is a fairly typical collection of national characteristics, in the same way that the British are obsessed with class, drink too much tea and alcohol, and say ‘sorry’ all the time. But the Korean approach to internet culture is fast becoming a new national characteristic. They have one of the world’s fastest broadband infrastructures, which makes online life pretty zippy.
