Interesting suggestions. Obviously one that would impact everyone the most if "Remove Social Rewards".
I fully understand concept behind it (reducing inflation), however if we do that - then what insentives would content creators have to continue using HIVE?
Wouldn't you expect, that this change would result with all communities turning into little ghost-towns? Also wouldn't you be afraid, that many curators supporting quality content would simply power down, seeing that there isn't enough content to support. And knowing, that their upvotes actually are having no value for anyone but them?
After all: if we remove rewards - then what in return would content creators receive? More traffic? More visibility to their publications? Anything which would help with content discovery and attract more viewers to their posts?
At the end of the day content creators need to have a reason to put an effort into their work.
Another challenge I see: how not to create wave of panic if authors would realize that all they have worked for is going to be done and gone?
