I think that Khan Academy is providing small nuggets (videos, quizzes) of content.
As a teacher, I can take Mr Khan's currants and bake my own cake with them (i.e. use their stuff to support part or all of a course). I pick and choose, but of course my students know the site and they can pick and choose as well.
