Thanks for posting this, I was not among those who downvoted you. Regardless of whether your proposal is in itself worthwhile, it's very important that we all consider the issue you raise. Last night in the CB, we had monks from five continents! This is fantastic, may the international nature of the site continue to grow! But how? How can we encourage as wide as possible a participation without breaking into separate langauage enclaves? Let's keep asking ourselves that question.
Personally, I like the option where everyone is free to post in their own language, where people pitch in (as they have in this node) to add their own translations, where there is a filter available to hide nodes in languages we wish not to see. Yes, that's a lot of work but I can't think of more important feature for the site in the long run.
