I just learned of Duolingo from a friend studying German. I've tried out the interface in English->Spanish study mode and I think it would be great for practicing sentence composition and translation - I haven't tried out the higher level exercises because my Spanish is pretty rusty, but the reviews seem good.

Anyways, they are continually adding new languages. And their twitter feed

says they will hopefully be adding Chinese in a few months.

So if you want more sentence/translation practice, check it out!

Yea I saw this about a year ago and signed up to do the beta selecting Chinese, but when they did the beta it wasn't there and then other languages have constantly been leap frogging Chinese. I agree it would be a great learning resource, but am slowly losing hope that Chinese will ever be added.

I spoke with one of the project dev guys from Duolingo at ACTFL in November, and while they haven't forgotten about Chinese or Japanese, it seems that other languages will be coming first.

I look forward to trying out Chinese as well. And having Japanese in there would be fantastic.

Haha, what?

Duolingo have said they're switching from adding languages themselves to letting users add languages. And they're currently working on the tools for users to do that.
