Build-it.io & @skatehive come to mind for me. If your students want to use this blockchain as a creative release, they could do things like teach/show people how to do things like build stuff or show their learning process.. or if they are interested in action/extreme sports they could post some tutorials about the sport that makes them the most stoked.. or they could really put their minds to work, and think of what the next unfilled niche is that needs to be filled and since they are entrepreneurial they may look at designing and creating the next tokenized community.
but for the folks who just want to dip their toes.. it is enough to provide value just by using PeakD to document their own life experiences, and at the vary least, to engage with those who are choosing to add content to the blockchain. there is many way to add value, and it dosnt always involve adding content. there would be no value without the "desired audience" being there to enjoy it, and to assign the value to it.
so they can either choose to be a content creator, a content curator, or and infrastructure developer.
-I didnt fully read the post, and criteria haha.. but that was my honest opinion.
