Today, I created the article for "deviantART" on Japanese Wikipedia, as English's translation.[link]
The article, however, have not been linked from other articles at all now. Only one description for dA was found in a pornography article, which was saying that "dA is the amateurs' pornographies site". (Of course, I immediately deleted it.)
dA, regrettably, seems hardly to be popular among Japanese artists yet. Especially, among anime and manga-style artists, like me.
Some of them don't know dA at all. Some others know dA, but they don't want to join by their English-phobia. Or, some others believe that Japanese need no opinion on anime-style from foreign people.
Though these situations will not change at once, I hope my article will help Japanese newcomers to join dA.
