This is a cool article that goes over the major search engines in South Korea and no...its not Google!
The overall design is more reminicent of a traditional web portal (Think Yahoo and AOL). Fascinating to see what South Koreans determine as useful with regards to search. It seems like they want more quality information about current trends and events than a clean interface. Naver itself has a pretty cool real time updating social network stream, now if only i could read Korean! Just goes to show you that one size certainly does not fit all, especially with regards to International SEO.
