I use Duolingo a lot! For some time I was learning Esperanto, but then when Korean came out I switched over. My streak went as high as 85, I think. I ended up losing it during a trip and got discouraged haha.
I'm hoping they release Indonesian Malay soon too.
Wooow a 85 Streak, never had such a high streak! Now i am pumped to get to 365 haha.
I am a korean newbie and just lvl 3 at the moment. The course feels a bit rushed, because you jump right into words and stuff without really learning the hangul basics. There are some nice hangul apps in the play store and i installed one to learn the basic characters alongside the practice in Duolingo. Really love this app.
Right?! They jump into it really fast. There wasn't much of a middle ground. They'll probably tweak it as they go along, since they're still trying to learn their way around teaching languages with different writing systems.
I hope improvements will come along the way. There is no real writing in hangul at the moment.
