How come German has such a bigger tree than all the other languages and when can we expect bigger trees for other languages mainly Dutch?
I don't know German, but I hear it's complicated. The U.S. government classifies it as a level 2 language for english speakers to learn, while pretty much all other Germanic and Romance languages are level 1. Also, I just can't resist saying this about the title of the discussion: PHRASING :D
Simius, one of the Dutch course team, says that Dutch 2.0 is ready to go, and they're waiting for the programmers to get back to them: https://www.duolingo.com/comment/22145163$comment_id=22196419
