I agree. Duolingo is great for learning vocabulary, but if you really want to learn a language you need to supplement this with listening to the language as well as speaking it.
I've been learning French and have been using Duolingo for vocab, but then I listen to a French-teaching podcast as well as trying to work on reading/speaking it.
