I like your proposal, more than @therealwolf's one, I see in his post some interesting points though, in general when he speaks about changing the reward system. That's also a weakness imo that wasn't solved in steemit.
But if we look into the most important failures in steemit, I think that the learning curve was too high. That obviously hasn't changed here because HIVE has the same infraestructure. In that way your proposal seems very reasonable to avoid that problem.
Anyways I consider that is very positive to see these new proposals and the winds of change that are coming with the enthusiasm of this new project.
