eBAY FOR KNOWLEDGE
I think it’s a smashing great idea, and amazingly simple. You want to learn something, sign up; you think you can teach something, sign up. Teacher and student meet up like seller and buyer on eBay.
The economic proposition is simple: you know something I want you to show me, and School of Everything will make it easy for us to meet and transact commerce to make this happen. It doesn’t depend on no one else being willing to do this for free, nor does it control what you do with the information once you learn it. Indeed, this is a service that benefits from the wider spreading of information: the more information there is about knitting, the more knitters there are, the more knitters there will be clamouring to learn knitting from an expert retained for this purpose. A knitting teacher doesn’t want you to hoard what you learn: she wants you to tell everyone about it.
