SkillTree

This is a collection of learning resources organized by topics, formats, difficulty levels, and quality tags like visual / interactive / challenging etc. It also includes reviews from experts and metadata like paywall/loginwall to help you find the best resource for your learning goals.

For certain resources like research paper or books, there will be direct links thanks to projects like InternetArchive, LibGen, Arxiv, SciHub etc.

This requires us to build a giant taxonomy of all human knowledge. Arranging topics in a hierarchy is not sufficient. Instead we are creating a graph of topics and levels with multiple types of edges: "is-a-subtopic-of", "is-a-prerequisite-of" etc. If you are an expert or educator in some domain, you can contribute to this project via our GitHub repository.

In conjunction with this, we're also building an online game where this is presented as a skill-tree for life and allows you to chase ambitious life goals and keep track of your progress while inspiring and being inspired by your friends. More on this will be revealed soon.
