Duolingo Japaneseって、Big Newsですね！
If you’re unfamiliar with Duolingo, it’s definitely worth checking out; it’s a really clever platform that, at the upper levels, actually turns the community of learners into a crowdsourced translation powerhouse. The app can be downloaded from itunes for free and, to my knowledge, doesn’t ever ask learners to purchase anything.
They have been offering courses for learning a few languages and slowly adding to the list, but they’ve just announced that they’re moving forward with Japanese as a target language for speakers of English. There’s a great article about the project on the Duolingo website, and I also saw a nice write-up by the Japan Times.
