A quick post here to direct you to a post by David Meerman Scott with a case study about how a self-published author created a powerful platform for her book using social media tactics.
If you believe the only way to get published and known is by being connected with a traditional publishing house, think again. Lisa Genova created enormous success for her book (a novel!) using free and low cost social marketing tools. Her efforts lead to a book deal with Simon & Schuster and it hit the New York Times Bestseller list. Read the case study and prepared to be inspired about what you can do to build massive visibility for your book or product.
