Basically, everybody can start a social media platform (or whatever content production service you want) and set up your own numbers. At that moment you will realize that the real bottleneck is not the distribution reward ratio
Who is going to rewards posts on that social media you speak of? what numbers are you refering to?
As I understand from the proposed implementation, other apps could participate in the reward pool and subsequently draw a part of it towards their own ecosystem, by using their own splitting schema. Think busy.org, with a different reward schema.
That's what I understand from Multiple Arbitrary Split of the Rewards Pool.
The Multiple arbitrary payout feature is a way for website like busy.org to receive a percentage of rewards earned on their platform but the distribution ratio issue will still be there.
In my understanding all content will compete for the entire reward pool, regardless of its source (steemit.com, busy.org), and the rewards are split differently according to each source/site algorithm. The distribution ratio may continue to be a problem in Steemit.com, but busy.org will have a different algorithm. That's what I understand, but I might be wrong.
