What does an advocate do?

Our friend, Ron Finklestein at Your Business Coach wrote a book a while back. Disclosure: He does not pay me to help promote his book, although he does host a website with another company of ours. Tonight I was at the local library and saw his book in the new book area. Being an advocate of his, because he has always been so helpful to us and because the book is good, I took his book down and did a face out for him. (I made the book stand with the cover out, more prominent.) A small act, but how do you get your customers, employees and other advocates to take advantage of small opportunities to create more visibility and buzz? That simple act may lead to someone reading it and hiring him as a coach, resulting in a significant amount of income. In this case, I can tell you that he has been involved with us for years and has consistantly cared about our success, and likewise we care about his.
