If a community has grown a lot, unfortunately it takes up all the posts on the homepage. If I were a developer, I would sort by weighted success. For example, if the “x” community has 1000 subscribers and the post gets 100 likes, it has ten percent success. If the other ‘y’ community has 100 people and gets 11 likes, it has 11 percent success. This overrides the post in community x because the post in community y is more successful. This is the logic of ‘weighted success’. With this logic, a better ranking formula can be created.
They are making a profit in the existing system. But they are ruining the business by acting on the urge to make more Profit.
