Many authors offer excerpts and samples of their books to prospective buyers. Do you like it when authors offer
• A free sample in e-reader format
• A blurb included in a review
• A chapter or more in exchange for an e-mail address
• Tweets or Facebook posts automated to share the same tidbits of text over and over and over again (really?!?)
• A blog or Web page that shares a part of the story and invites reader comments and question
Which do you think your readers will prefer?
