Seems a really good idea, however I looked at:
http://news.unbabel.co/fr/fobo-est-presente-a-san-francisco-...
Vs.
http://techcrunch.com/2014/01/10/fobo/
and the translation, by _5_ people, is really poor: Just look at the first line :
>Maintenant, vous sauriez déjà que Craigslist n'est pas bon comme un lieu pour vendre votre produits.
This translation is unpleasant to read and has some mistakes. Google translate gave me a better translation.
I guess the problem comes from the fact that translators are not native in the target language. When you use the product, can you request native language translators ?
