Essentially, SocialBook, as [Bob Stein] calls it, will be a website that allows publishers, readers and writers to upload books, new and old, so they can be read and discussed interactively. The book will appear on one side of the screen with a commentary panel on the other side. The uploads will be subject to copyright restrictions and the site will be curated in order to maintain quality. You might think of it as a giant book club, with potential for all kinds of adjunct activities.
