You have my witness vote.
I am honored ....

These are great real world examples that really put flesh on the bones of the theoretical stuff.

Usability like I mentioned above AFIK may not be possible after HF20 because of the RC limitations. ie, imagine we give accounts to citizen volunteers performing survey of roads. The volunteers may soon run out of RC to make any transactions on the chain. The implementation of RC in the first place was to fight spam but it has made the chain more or less "resource constrained" and expensive for the end users like EOS. May be the SMTs will create a situation where SMT holders can interact with the chain the same pre HF20 manner.

Unless I am mistaken, HF20 + no SMT is going to limit the usability of chain for generic purposes.
