As I see it, we are all feeling our way forward including the management of Medium. In your case, you need to start whittling away until you follow writers that interest you. There are so many people desperate to get heard and believing they have to write every day even when they have nothing to say. Be discerning and follow those that connect with you. Slowly your feed will start to point you toward them and filter out the rubbish but it takes time. I don’t see how anything this big could be any other way.
