It's unfortunate that some people feel they need to follow other people just to get them to follow back. Not only is that useless, but it will also pull down your Hubber score. The purpose of following is for one main reason, to be notified when someone you're following has published a new Hub. It is a known fact from people who have posted in the forum about their experiences, that if they never read any of the hubs of the people they follow, their Score drops.
I only follow people when I have an interest in the subjects they write about. I never follow people just because they follow me unless I found a Hub or two of theirs that I liked, and I want to read more.
Yes I will check out their list of Hubs when they follow me. And if I like something, I'll read it. Then I'll be able to make an intelligent decision to follow them or not, based on true subject matter and not for building useless lists.
