Many are saying that this is a bad idea and ending their comment with "and I say this as a non-native English speaker", but since you had to explicitly tell us this fact, you are not the kind of person who needs any kind of non-English SO or whatever! If your English is good enough to be (at times) indistinguishable from a native speaker, you are in as good a position as any native English speaker, on the Internet.
Maybe you are in a position to have more sympathy with people who can't speak English, since you used to be in that same boat. But it's not as if having an English-only programming community is of any detriment to you, personally.
