North Korea zone is an informative, requently updated weblog about North Korea. Recent posts include links to articles about Kim Jong Il's arrival in Korea aged around 3 or 4 in 1945, and references to academic papers about hidden South Korean aid to the North (Park Hyeong-jung."A Stepwise Scenario for Rebuilding the North Korean Economy." East Asian Review Vol. 15, No. 4, Winter 2003) and the involvement of some groups on the Japanese left in North Korean abductions of Japanese citizens (Patricia Steinhoff. "Kidnapped Japanese in North Korea: The New Left Connection." The Journal of Japanese Studies - Volume 30, Number 1, Winter 2004, pp. 123-142.)
Slightly off topic, one of the contributors reports first-hand from China on the restrictions on web access there - the site that hosts the blog, typepad.com, is blocked there: perhaps blogspot is too.
Of course, there is no internet access at all for the vast majority of people in North Korea, even people who work in the computer industry.
