Persuasion is what social marketing is all about. Persuasion is built into all of us...remember the nagging for that toy, followed by the cute look which was likely to work.
Business is about persuasion, leadership is about persuasion.
The social web is a great tool to persuade but there is one thing many forget...
When I present, when I coach...it is often the gap in what you are saying that has the strongest effect.
Just because social marketing allows you to talk all the time, remember....to allow that gap....to allow people to digest and 'feel' what you are saying.
