Skillshare is helping to enable community-based, informal education by providing an online infrastructure for organizing and promoting classes taught by skilled individuals. You can sign up to teach a class or attend one. Right now, all the classes are in New York or California but it is an interesting concept and I’ve seen instances of this phenomenon here in Minnesota. A few months ago I attended a beer-tasting class that was organized through reddit. Found at Vimeo from skillshare.
