share_learning

Introduction

share_learning is aimed to be a crowd sourcing open learning platform.

It collects courses links from MOOCS like Coursera, Udacity, Udemy, etc. and relating videos links on Youtube, and lets users easily find learning resources matching their familiarity to a want-to-learn subject / topic on just one website. Users can leave suggestions, tags, and ratings to each learning resource. They can also add relating learning resource links to each subject / topic.

But now it is still under construction. :sweat_smile: :beer:
