David has been on Goodreads since the beginning however this is the first time we are actually speaking about this resource. Directly from their webpage.
Goodreads is the world’s largest site for readers and book recommendations. Our mission is to help people find and share books they love. Goodreads launched in January 2007.
Goodreads is a great resource to help you find new authors, keep up with the authors you love to follow and find new authors to follow and see what your friends are reading. You can find David's author page along with all of his resources here.
