Hey Rmcrayne, I have RedGage and my Blog. I have also sent out some Tweets(Twitter).
I have done very little backlinking, however, most if not all my hubs are inter-connected together, so when one person reaches one of my hubs, they are most likely able to get to others, just like it(the one they visited).
I have no clue who is linked to my articles and so on and so forth. I do no promotion(advertising) of my hubs. Except as I stated above. Then again, as I've said plenty of times recently, most of my revenue generated is coming from my Photo hubs of Models and Celebrity Hubs, at least 90% of the total.
