If you are on the social network at all, you know the people who promote until you want to stab yourself in your eye so that you don't have to see them any more, or the people who overly/fake gush about how surprised they are that you "like me, you really like me."
So, what draws you as a reader to buy a book? Word of mouth? Favorite author? How to you pick new authors? Contest and award winner? Does promotion matter to you as a reader? Inquiring minds want to know. Cheers~
