11.9 million Korean bloggers

KOREA: Kim Tong-hyung reporting in today's The Korea Herald that Yahoo! Korea has about 3 million weblogs, that Naver has 15 million registered bloggers (5.5 million active), and Cyworld has 11 million registered bloggers.

Assuming no overlap (the naive assumption) and that they all have the same 37% active-of-registered-bloggers (using Naver's figures), then Korea has 10.6 million active bloggers. Can I improve the figures by including an overlap fudge factor, users with active accounts on more than one system? Not much. Let's assume 90% of the users are loyal, fair given we're talking about active bloggers. That puts the population of active Korean language bloggers on these three hosts at 9.5 million. Let's assume that there are 25% more on other Korean services. 11.9 million Korean bloggers.

Four things:

1. Why aren't Technorati, PubSub, and BlogPulse recognizing and monitoring those blogs? Are these three not pinging, or pinging somewhere unknown?
2. Common sense (and a quick peek at LiveJournal stats) shows that people prefer to diarize in their first language. So how many smaller hosts are running blog services in Korea?
3. There is no reporting on how many Korean language bloggers are in Korea or overseas, in the Korean diaspora. My favorite internet cafe in Oakland, California, is run by and for Koreans, all systems bilingual. The Internet is a strong link to Korean news, culture, and families. (Skype has gotta be huge, but that's for another blog.)
4. Korea and Korean may be displacing the United States and English as the center of blogging. Certainly, per capita. I can't wait for the Korean blogging conferences to start.
