Periodically, I just browse through a long line of hubbers. I add almost all of them, avoiding only the really strange (psychic fortune tellers and witches, e.g.) writers that I will never read.
Then, some percentage follow me back.
The other way is to leave insightful comments. Some people hype the joy falsely. Not me, I want to be me, and have a personality. Better to lead than to go with the flow.
I personally will follow a hubber after reading a great comment. They have something to contribute, right?
