Almost the polar opposite of the current MOOC craze - small-scale, paid-for (but cheap) classes, mostly (but not entirely) not online, mostly highly local, mostly very personal, entirely non-formal but not informal. This is about passing on knowledge of elders to the next generation. The online site is an enabler and facilitator of local, human learning, occurring in a very traditional manner that might not be unfamiliar to someone born hundreds or even thousands of years ago, but scalable for the Internet Age.  

From the site, explaining who this is for...

"Anyone who wants to learn but hates formality. We want to make learning more fun, more friendly, more social, and more personal. If you want certificates or diplomas, keep on walking. If you're interested in learning for its own sake, we've probably got a class for you."

I like this. Nothing much new, but assembled in a novel way that is anything but traditional.
