Idea: Language chatrooms
I just had the idea of different chats for each language where learners and native speakers could chat with each other. That might be a good start for people who are not yet confident enough to write in a chatroom full of only native speakers but want to try their language skills somewhere. Each Duo Language would get it's own chatroom where you can ask questions about the countries or just practice a little conversational skills.
Splendid – the next step for many of us. There's an enormous difference between working through a lesson compared with responding to someone in real time. And unlike other areas, people would not be there for points (the quest for points appears to distort the dynamic of some activities).
I'd prefer to err on the side of inclusivity rather than exclusivity. There are lots of folks who haven't even reached level 12 or so yet, but can nevertheless manage to carry on a fairly good conversation. And certainly native speakers should get an automatic pass.
However, after following Samsta's suggestion and checking out a few German Chat Rooms, I can see why some limits may well be required.
