Yes, Learning Spanish is worth it. I mean, I also started Duolingo out of interest. And a few years ago, because I learnt Spanish, I went to Mexico for an interview and I actually spoke to the locals in Spanish! It was fun. So yes completing Duolingo is worth it, but only if you are putting in the work that you need to learn another language.

Learning Japanese with Duo. Definitely not the best. I reached Checkpoint 6. One year left to go. I can barely make out a sentence in Animes.

You know what? Duolingo is Crucial. Not "all-encompassing / one-stop-shop", but it definitely makes you progress. Once I complete I will migrate to Memrise, aiming for the JLPT's (high-level Japanese). Duolingo will not make you an expert, but will get you started well into the basics. And for basics, there is no-one else who compares that is as fun and requires as little commitment and no punishment!

Btw. There are 2 types of Animes. One for Adults speaking high-level Japanese, the other for kids with lower requirements ..I do better on kids' cartoons like Pokémon!
