The problem I see with this post is that it seems to imply an assumption that those in the foreign section of the forums lack the capacity to communicate in English. Believe it or not, English is a rather popular language around the world primarily because it makes practical business sense to be able to communicate in both English and in the native tongue. Here in the Americas, Hispanics who speak primarily Spanish usually grow up understanding English as their second language for several reasons, one of which involves immigration into the US which is a touchy subject. Chinese learn English as their second language as well. CCP Games has its headquarters in Iceland where Icelandic is the native tongue but they still communicate in English.

Air traffic controllers and commercial pilots around the world often learn English because that is often demanded by businesses for being able to fly/handle international routes where everyone from different countries have to be able to understand each other to avoid mid-air collisions.

The translation of the announcement to different languages is of course important, but it just makes practical sense to have those people in foreign sections talk in here in the English section if they want to give feedback. If they can't speak English at all, that is OK. There are always personal translators to help around. Although I would advise them to avoid using Google Translate at all cost.
