So far, 2 out of 7 participants of this thread are native Japanese. I say it's not bad. Actually, this forum have way more Japanese natives than any other English forum I have ever seen. Anything more than this, I think you'll need to go to Japanese forums like 2ch, mixi, 発言小町, はてなぶっくまーく, etc. or may be more language exchange kind of places like lang8.

I don't know much about the history of the forum. I've been around only for a month or so...
