Language Learning Platforms

I am just getting started with the Stanford University - Venture Lab class on Creating Education Platforms.  It is great to see people from all around the world creating environments to address communications needs between what I call traditional and non-traditional languages.  These environments go above and beyond just simple desire to learn new languages but are in many instances driven by the needs of various humanitarian organizations trying to establish some kind of a communication mechanism with those in need.  For example, below you will see Busuu, a language that is spoken by 8 people in the entire world.  Or Pictason, focusing on the language that is spoken by a small tribe in Morocco.   There are some great efforts and examples, see below.  I will share more as I come across them.
