Great summary and comparison. Yes, one thing I worry about with blockchain is the centralization of ownership of exisiting companies, and that the elites will funnel everyone into their "decentralized" systems that they back/create, but i'm too ignorant to understand the real fundamentals here.

I just continue to be surprised how few peole worldwide can figure out how to get on STEEM blockchain... it guess the "it" factor is not quite here. (-:
