I think that a potentially big audience that we should consider (and that would benefit significantly from this work) are Mandarin (and Cantonese?) speakers. In that case the “bubble” that @vmagnin has correctly described is much ticker and more resistant.
The problem is to find someone able to revise the automated translation that might be very poor. I know that it’s a tougher problem compared to what discussed so far, but I think there is a lot of untapped, rising potential among Chinese developers and the effort might pay dividends. (And no, unfortunately, I don’t know any Mandarin and Cantonese, unfortunately 
.)
