Yeah this is very helpful post to upcoming HF21. Su i wanna thanks to you for great explain. But i want to leave a comment about downvote pool.
As you know some individiuals or gruops have fighting each other. And we always see some little fight on blogs. But with this change on downvotes we can see bigger fights. Maybe it provides to much better content quality, but at the same time it can bring us new war gun. Actually this will be so dangerous for future of platform.
As you mentioned many curators will not change their behaviors. So many people on steemit will wait own whale to upvote qualit content. I have been for 1,5 years. And already many groups on this networks and already they upvote just each other in same group. So how can change this people behavior. Because already they created own group economy.
When you read all this article about new changes, it seems great. But this is just great for huge SP holders and whales. Many people will wait their miracle whale to see him/her. This is really hard way to all steemians. I hope i would be wrong about my thoughts.
But again thanks for explain. Have a nice day.
