As far as I'm aware, it's the only service that lets you easily find out whether a book is part of a series/universe, where/how it fits in there, and notifies you about upcoming entries in series you follow (email notifications have never worked for me, but at least you can check on the site). Essentially series/universe discovery and news. This used to be massive painpoint for completionist me before Goodreads. If anyone knows of any alternatives I'm all ears by the way.
