No matter how many times I select "Not now," the option will not disappear.
But if I do select to use it some day, it would be nice to have some control over who and what publications appear. I like the idea of the most recent being at the top, but I also think there are some good writers who don't publish all that often. We should be able to highlight at least some of the writers to stay at or near the top.
What would be nice, too, is too see not only who you follow but who follows you back. Twitter can do this; it would be nice if Medium could, too.
