Readers want more than just an author's work; they also want to know what kind of person the writer is. When writers can bridge the distance between themselves and their readers, and become the "in" writer of the moment, there are more opportunities to develop product tie-ins. This kind of relationship also helps their book sales.
因為讀者除了喜歡作者的作品外，他們也渴望了解作者本人，如果能拉近自己和讀者的距離，甚至塑造某種「人氣作家」的流行感，相關周邊的商品開發可以更加多元化，同時也有助於圖書銷售量。
