You know what would be great?
You know what would be great? If duolingo had an option to have tutorials with a real person. Like if you were to call someone from another country and that person can help you out with whatever you need help on. That would be an amazing feature to have!!!!
Thanks. It depends on your perspective. Personally, I'd prefer to see improved quality over expanding into most other areas unless there's a really good reason for it. There's no way one app could do everything and they are already pulled in many different directions. I use several other resources in addition to Duolingo.
I often have people to talk to in person, so haven't used online language exchange, but you might want to check out this post. http://www.fluentu.com/blog/french/french-language-exchange-partner/
