Once you follow a hubber, you will be brought to a page which says "You are now following xxx" and the hubbers who are also being followed by the hubber you are following are also shown in that page. The page says, "xxx (the hubber you are following) is also following the following hubbers" and their profiles are shown there. I hope I answered you correctly because I am also new to hubpages. What I am telling you is based on my personal experience here. Thanks and God bless you.
