Additions to immersion
In addition to articles, how come there are no videos or other sorts of media yet (at least for italian)?
Both Duolingo and Livemocha (Well, Basic Livemocha) lack those things. I really think that these stuff are essential for learning. Personally I read french journals and watch some videos on my own but it would be very nice if It was provided here on the site altogether with lessons.
I agree that video and audio would be nice additions.
The answer to "how come there are no videos" is simple: Duolingo gives articles not only for us to learn and practice, but to translate and return something useful to Duolingo. The articles are provided by customers who, depending on the type of document they uploaded, pay for the translation.
