This is the kind of thing I find much more interesting than another attempt to make people “engage” more.
The part that really stands out to me is “you don't actually have to talk to each other, just do your part.” That's pretty much how I think decentralized systems should work. You shouldn't need every frontend, developer, or user to coordinate with everyone else. Give people a common standard, let them build independently, and make the information they produce legible to everyone else.
I've always thought Hive and Blurt are more interesting as semi-permanent records of people's work than as places to farm votes and rewards. The blockchain already has a huge amount of information sitting there. Making that information actually useful and interoperable seems a lot more valuable to me than creating more layers of behavior around the reward mechanism.
If this can actually get us closer to “post once, have it understood everywhere” without requiring everyone to agree on a single frontend, that's a damn good direction to be pushing.
