I wonder why German gets no translation since long; given the number of German Wikimedians.

It's less surprising for Korean even if (South) Korea has excellent level of Internet coverage since long (but also its older and popular cooperative and social platforms, explaining why Wikimedia is not so successful there). But may be most Koreans don't feel the need to translate English (because many of them have excellent education levels and can easily read English; but educated Koreans may have chosen another secondary language than only English, such as Chinese, Thai, Indonesian, Japanese, Spanish or Arabic and would like to get translations from English to their primary Korean language).

Or may be there are specific difficulties for translating technical English to Korean (we are speaking about tech news here, not general news, songs and poems). It's rare to find technical documents written in Korean on the Internet (much more than in Chinese or Japanese).
