I read SO for tech stuff. I am trying to contribute more, and when the Japanese language beta came out, I racked up 300 points in 3 days. Then I got tired of it. People spend inordinate amounts of time on miniscule differences between two words, when they aren't even conversational. That's not how I would learn a language. When a Japanese person says two expressions mean basically the same thing, I take their word for it; I have bigger fish to fry.
