Good point. Answering to you.... I know it is only a spoon of water into an ocean but my idea has 2 different points... increase the reward and decentralise the SP giving delegated SP to other people but owning it anyway.
If you have more SP your vote worth more and will reward you or the people you up vote more. You will get more curation reward as well.
For example with my 5million of Vest power I can give 3 cents for every up vote.
My idea is a draft that can be used and modified giving a great result.
