An interesting theory Tom but sadly the reason most use Social Networks is sheer boredom, believe me, I reach out to these people 10 hours a day..
NorthFace, it is important to find a balance in content, there are 2 important factors to remember aside from the basic rule that 'Content Is King'.
1. Your following must be educated with relevant content, whether it be news posts, facts or highly opinionated content, the most important part of all of this at the end of the day
is brand building, with that comes reputation and influence.
2. Virality, you won't get very far without 'Shares' therefore you will require the occasional post with some comedy value, I tend to post 2 factual posts and 1 comedy post per day.
Abiding to these rules has allowed me to successfully navigate around 50-60 clients to a very influential state.
Best of luck!
