Nurture your advocates. Know all your best customers by name. Provide above-and-beyond incentives and surprises to the tribal core. A small business may invite the best clients down for a Friday afternoon barbeque or an evening of live jazz. A band may offer a full-length show available for free download to street team members. A retail site may offer added incentives to the best affiliates. The people that are well cultivated and treated with respect become the very foundation of your growing business.
