Interesting article. We actually just had a discussion on this topic the other day at work. Oddly, or out of best practice, whatever you want to call it, we try to keep all code documented in English, written in English, etc, but almost everyone involved on our projects would understand it better if it was in the native language. I do sometimes wonder how big of a difference it would make in the community, since most coders just read the source code anyway. I've had to work on a couple foreign language code bases in my life and it wasn't anything extravagantly difficult. Though, then again these were all european languages where you more or less know what something means if you speak a couple anyway, that's not the case with something like chinese or arabic. Anyways, I wouldn't mind not forcing the "everything" in English, I think if it was a looser atmosphere more people would get involved.
