Bring justice to duolingo!

So there are some memes about "dUoLiNgO sEnTeNcEs ArE aBsOlUtE gArBaGe BeCaUsE yOu'Ll NeVeR uSe ThEm" and that other language learning apps are better. However, once you think about it, if you're actually gonna speak that language, and on duolingo you see "The elephant is reading the newspaper, " and you want to say that a person is or was reading the newspaper, it's a bigger challenge and requires you to remember the word for person or whatever and plug it in. Duolingo, on the inside, isn't just random sentences, but made for deeper understanding, not memory.
