most customers: consumers and organizations are not really interested in such engagements. They don't want to be "fans". That they turn off after so much blather on their screen and in their ears.
Moreover, customer loyalty is fickle. A product or service that shines in the first instance may stink in the second either in the manufacturing, delivery or price, which means bye-bye buyer... There are still a large number of social and other channels and channel providers to pick from. The smart ones will make enough but are not so greedy so as to drive away the very source of their profits while satisfying or at least not annoying the customers. For it is best to have disinterested customers than ticked off ones.
