As a former language teacher... (Score 1)

How many of the people involved in this project have studied second language acquisition? How many have actually worked as language teachers? None, I suspect. Just like Duolingo, Rosetta Stone, Pimsleur, and all hyped language learning programs before, this will do little to actually help people achieve proficiency. Some people might gain a little competence, but there's a huge chasm between competence and performance. This is nothing more than "language learning + [what's hot at the moment]."
