Aspects

Given the insights are tagged with aspects, we can filter over the linear content progression and create learning sub-paths.

These sub-path progressions will most likely not cover all content, but they will ensure and enforce an unified learning experience, tailor for the user wish.

For example, a user might be interested in new additions and updates of a language, rather than introduction lessions. Note that these sub-paths don't take games into consideration
