Setting a language on tribes

I posted my first snap and noticed that it went both to the tribe I meant it for, and to the frontpage. Touble is, I'm more interested by the nascent french-language tribes than the ones in English and if we all start posting in tribes of our various languages we'll eventually get a language soup on the front page.

To fix that, we could assign languages to tribes (could be more than one, for instance /t/Switzerland would have four) and use that for preventing snaps from reaching communities that don't speak the language they were written in.

Also Snapzu itself could be localized but that's a much smaller concern.
