Overall....OUTSTANDING direction, simplifications, and some improved frameworks.

Thoughts:

1. Really like ALL the KISS clean-up and simplification. Old unused features will become caustic over time. They are a liability, so it is good to get rid of them.
2. I like the 7day, versus 24hr rewards.
3. BUT... why can't there be a rolling-30 day payout for upvotes after? This would promote quality posts which are relevant over longer periods of time. Exactly what we want! Just because the metrics show most payouts occur in 7 days, does not mean it is strategically optimal for the platform or usages. For example, what if an author wants to write a novel. Each post is a chapter in the story. Why shouldn't a year from now, when a new fan starts reading the book, a payout can be earned from chapter #1 and so on?
4. I like the independent comment reward pool and the effort to encourage more interaction by members (I think that is the strongest aspect of Steemit, an active community with a LOT of interaction).
5. But, 38% of the rewards seems WAY high... Until we get more people eased out of being shy, it might promote lower-quality/higher-quantity comments. Perhaps start lower and ramp up from there? Just an idea.
6. I don't understand the "Separate Market and Rewards Balance from Checking and Savings". Seems like an overly complex system to be added without a clear benefit. Does this basically add another 'account' for users to view/manage and understand? We already have Steem, Steem Power, Steem Dollars, and Steem Savings... This would add a Steem side-account? Whoa there cowboys/cowgirls. Let's refer back to your KISS principles.

And as always, thanks again for your continued work to make the platform better. I appreciate everything you guys/gals are doing and the fact you engage the community on future change proposals!
