Dan, another great essay. Beautifully written.
My only quandary while reading was that of "critical mass." The viability of any blockchain, irrespective of aspirational intent, is dependent upon its adoption by a network of users. And, at some point, there is a number below which it simply does not function. There is an "emergent" aspect to all this and the positive feedback loops required to make everything work simply don't happen.
STEEM/Steemit currently has approximately 12,000 active users. Whatever its critical mass, it cannot be much lower than that. The same could be said for 98% of cryptocurrencies ... and any potential spin-off of STEEM.
