Duolingo, learn a new language while translating the web (duolingo.com)

Previous discussion one and a half years ago:

so cool. started learning german :)

I tried this out because I know a little French and would like to know more.

I was first put off becuase when "Je suis de Anchorage" (which I'm pretty sure is not idiomatic anyway) was expected, "Je suis d'Anchorage" (which is correct within the scope of the already unidiomatic expectations) was not allowed. Granted, French is still in beta.

Then the audio portions produced... no sound. It's a bold move for a web site to depend on audio. I recommend making sure it works first.
