Plans for Danish?
It seems to me that Danish shares many grammatical similarities to English, and it would be really cool to be able to learn Danish through Duolingo's interface.
At the same time, I understand that the amount of web content in Danish may not be very large, and hence it may not be advantageous for you to spend money supporting a language that won't create revenue.
Nevertheless, are there any plans to add Danish in the future?
There are no plans to add specific languages like it was done before, but there will be an option for the users to add languages. This will probably come this year and if there are enthousiasts who can make a Danish course, there will be one.
