I'm using Duolingo for French, too! If the rest of you language-learners haven't checked it out yet, it's a pretty cute app/site that makes a lil' game out of learning the language. (They have Spanish, German, and a couple others available right now, too.) My favourite part, though, is how natural the learning process feels. They teach you a few words, then throw in new things and recombine things you know in new sentences, so you learn through figuring out and getting comfortable with words, rather than memorizing.
It's also in nice bite-sized chunks, so you can work at it for a while if you want, or just do ten minutes a day. My buddy does his French lessons during his poops.
I've also started watching movies in French, which helps keep me pumped because it's so excited to know what someone is saying every once in a while! It feels like all that learning is doing something! One time a child at the subtitled showing of
Ernest and Celestine said something to her parents about me in French, and I understood it! Proudest moment.
I also know Russian, but that's because it's my first language. I actually have no idea why anybody would ever learn Russian -- I can never explain the reasoning behind any of the grammar rules when I'm helping friends study, and there's all these exceptions, and it's just silly.
