The answer to your questions are in my last 100 posts.

Steem is an experiment (says it on the last page of their whitepaper).

It is all about lining their own pockets as much as possible, they have zero intention of making this actually function.

By making curation more profitable the whales that do little to nothing other than line their own greedy pockets can further profit.. leaving all of the creators in the dust.

It has nothing to do with giving you the user a better experience, it is just about squeezing as much money as possible out of this puppy before the total implosion.

Lastly 40% of the top 20 witnesses are in power down.

60% of the top 100 witnesses are currently in power down.

They know it is done. They are trying to trick people into buying in.. so the price doesn't tank as they exit. Then you will all be left with nothing but worthless shit coins.

Cheers
