What do you class as "traditional methods"?
In the flesh teachers.
My MOOC successes have been ones that introduced me to subjects for which I subsequently got hold of several books, or ones that supplemented parallel study in a similar area.
Yep, this is what I end up doing. Works pretty well for me.
You know the drill - If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
