If I had the programming skills I would like to create a .io domain that works off the steemit blockchain as a decentralized kind of learning platform similar to something like Udemy.  Members of the steem community who were experts in a subject could offer on-line lessons that they would be paid for and users who wanted to learn a subject on their own schedule would be paid to learn and rewarded based on testing proficiency. There would be areas of the website for study group forums and independant study.
