“Why should we divide our friends and fellow readers up by the devices they use?” the BookGlutton.com founder asked in this article in Publishers Weekly.
Readum allows readers to make comments on specific paragraphs in their books. Those comments are then posted to Facebook groups or their Facebook wall. The app also creates an individual page for the comments and pulls any book listed into their Facebook profile.
The app is limited to Facebook users at the moment, but Twitter support is planned, according to Aaron Miller of ReadSocial. Miller went on to say that by using ReadSocial API, developed by BookGlutton.com, developers and content providers will ultimately be able to tie any e-book to any social network or community.
