One of the most wonderful sites I’ve ever found that is dedicated to readers is Goodreads.com.
The members of Goodreads are passionate about books and communicating with one another their preferences. You only have to read the reviews of a new book to realize how committed the members are to their shared passion—all things books!
The site allows inter-communications via email, members to follow others’ recommendations, and be-friend one another. Members have personal pages, and authors can build their own pages, linking their books, posting on an internal blog, and adding a review widget to their web site to name a few items.
I was able to start a dialog with many of the reviewers who showed an interest in character-driven, space-opera stories. This led to a priming-of-the-pump, so to speak, of my own novel before it was published on Amazon and has set the model for my future efforts.
To the members of Goodreads, I doff my hat. They are a superb bunch of people who care for the written word and the stories of authors.
