I want to suggest Free TON Community developers to build a debot named Light Earn/Crystal Earn which have a motive to empowering learners for their gained knowledge about Free TON ecosystem.
Lessons created and their incentives must be passed by community voting.
User need to start with reading or watching basic lesson based on Free TON ecosystem and then answer some random questions based on that lesson.
User who passed first lesson would earned some crystals and automatically goes to next lesson and so on.
An example of such platform is Coinbase Earn.
