A thoughtful and on its face practical sounding suggestion.

Although I've seen somewhat of a reduction in spam comments lately, I think your idea would help reduce them almost to non-existence.

Actually, the entire reward mechanism at Steemit needs an overhaul, but I don't have any original ideas at the moment. I'm glad to see that @mattclarke chimed in here, as I've also found his ideas appealing.

Steemit desperately needs some change to rewards that would encourage a change in the balance to a mass quantity of reader/curators supporting a smaller number of quality content creators.
