Please see this knowledge base article:
When I click on my profile and then on the "following" tab I cannot see any ":follow" by the authors.
You are correct - the tab you are referring to doesn't break out authors separately (this is something we will upgrade in the future). Each card does show whether the individual is a contributor or not allowing you to eyeball and unfollow anyone you wish to.
thanks for your help. I understand how it works now!
