Months after Duncan Watts published his article basically calling the Tipping Point an irrelevant concept, the debate still goes on about which theory is “correct”. Personally, I tend to agree with Joe on this one:
A year later and a little more to the point, here’s what marketers can consider: Everyone has influence, but that influence has a couple of variables.
–People have a quantity of influence: the maximum number of other people they can reach with a message.
–People have a quality of influence: the amount of influence they exert over those that they reach.
–People have types of influence: categories of “expertise” that other people assign to an individual.
