This proposal is a steeming pile of hot garbage. You're tinkering around with rewards incentives that pull rewards away from authors to the tune of 25% without addressing the biggest problem Steem has.
EASE OF USE.
You want to make Steem better, make it easier for newbies. Every one I've signed up has given up within two days of using the platform because they get confused and frustrated! They don't get enough initial SP to vote enough to explore and they leave!
Meanwhile, you're proposing taking more rewards away from me and fellow authors. I spend HOURS creating thoughtful content. Researching, writing, photo editing, video creation, et al and you want to make it even harder for me to earn my small rewards?!
This "big picture" mentality truly misses the point. Without authors, you have NOTHING. Absolutely nothing and if you make it less desirable to create, authors will leave. Coupled with a lack of focus on end user experience and you've got a poison pill and then it's bye-bye, Steem.
