You've heard of barter flea markets, but who knew there are such things as barter schools where you can learn something new in exchange for your own knowledge?
This November, The Substation is hosting the School of Uncommon Knowledge, where you can obtain life experiences from everyday people at no charge at all. The lessons come simply at the price of exchanging knowledge and services of your own — and everyone gets to learn or receive something new at the end of the day. A brilliant concept, really.
