I believe the reason of following a post or a person or an author must not come from "You must follow me back" attitude. If you love what you're read, then you should follow it if you want to hear/see more of that. It shouldn't be always about money.

Agreed. Those usually end up being "empty follows" anyway, @tiffanyrej. I have seen fairly new accounts here that follow 5000 people, even more. Do you have any idea how much time it takes to follow that many people?

But I am not into the whole "follow-back" thing. Either someone is interesting-- and I will follow them-- or they are not.
