From time-to-time I will randomly select fans from letters, emails, my blog, Facebook, Twitter, YouTube or LinkedIn sites and send something free. Who knows, maybe a free product or gift certificate, or small token of my appreciation just for being a fan. As a self-publisher my success depends 100% on fan referral, reviews, the grapevine, and coffee-time conversations. When I hear people helping me, I want to help them - that is my nature.
