Luis von Ahn is the creator of Captchas - those skewed words you see all over the Internet. Over the last year he has put the knowledge from that into making a new language learning system that is totally free, and also can help translate the Internet! He gave a TED talk about it (both in English and in Spanish - he is from Guatemala).
I sat down with him over Skype and asked some questions in Spanish. Sorry the video of my side isn't included - I recorded it separately, but lost it. Recording a Skype conversation was harder than I thought, even with paid software.
