Because apparently most people are like me and do not follow any pubs, only individual authors.

I do not submit to pubs and don’t accept submissions. My pubs are for organization only and I am working to cut them back to only two or three.

If Medium had a better way to organize, I’d scrap them all.

How? Well, they canned all their own pubs for starters and the new mobile app exposes authors, not pubs. Read Mediums blog entries.
