We can-all you have to do is go to the person's profile page and look for a gel cap shaped button above the biography. It looks just like the button you click on to follow certain topics on the topic pages-for example, I follow "poems and poetry," "classic movies," "music," etc. If someone publishes a hub on these topics they will show up on my home page once I sign in. You will see it gives you the number of people following. If you are following the hubber, it will say "unfollow." If you are not yet following this person, you will see "follow"-plus the number of followers the person has. It's just more discrete now and you have to see the person's profile to do it.
