Pros：From my point of view ,the* most immediate benefit is that I can talk with many people who come from different countries around the world online. Learning* certain languages* can be possible in this way*. Cons：When I talk with my foreign friends ,a translator can be a useful option*, but* sometimes translators turn their messages into gibberish.This is very embarrassing. Starting language with foreign friends is seems that very easy. (Perhaps you mean: *starting to learn a language with a foreign friends seems easy, but it's not*) But when we talk with each other ,we* always need to spend a long time to introduce one another ,Even we sometimes must talk enough, and then we can start our journey of language .It seems that just for chatting not for language . (Perhaps you mean: *but when we talk with each other, we usually spend a long time introducing ourselves to one another. We must speak a lot in order to be able to start our language learning journey. Talking with foreign friends might be just for the sake of chatting, not really for language learning*)
