"ou can only speak and write English so how do you converse with a person in China who writes Mandarin but doesn't understand a word of English? Google Translate is no doubt a good option but it is going to be tedious for you (and your Chinese friend) to translate each and every sentence manually before sending them through any messenger."
Seems cool for communication/collaboration possibilities in foreign language. Could be an interesting way to work with pen pals in another country.
