The Japanese offshoot of the Korean company Naver, with its search engine (UA "Yeti"?) and other services, has apparently suspended all those services on December 18. Announcement still up at [naver.jp...]
Then we didn't hear much from Naver Japan in terms of search. They never sent my sites much traffic. But in 2011, they launched the LINE mobile chat application which has taken off worldwide.
The change in Naver Japan's direction toward more social media and mobile makes sense. Their search only sent my sites a handful of visitors over the past year, and they are once again exiting the Japan search market. I wonder if they will try again some day...
