North Korea using Twitter and YouTube

The New York Times carried an interesting article today on how North Korea is using Twitter and YouTube to bolster its propaganda efforts.  During the last month, a series of video clips have been posted to YouTube, brimming with vitriol and satire against leaders in South Korea or in the U.S.  During the past week, North Korea also began operating a Twitter account under the name uriminzok or "our nation."
A spokesman for the National Unification Ministry in Seoul said “It is clear that these accounts carry the same propaganda as the North’s official news media, but we have not been able to find out who operates them." The two Koreas agreed to stop their psychological war after their first summit meeting in 2000, but the situation has changed following the sinking of a South Korean warship in the West Sea earlier this year.
