Hacker News Reader

Calibre can integrate with Goodreads if you use the plugin in Calibre for Goodreads. This way you can synchronize your shelves and progress. There's an obvious downside to Goodreads: your privacy. Having all my privacy settings as high as possible, I do like it, but a data leak would expose my personal data.

Unfortunately goodreads looks like its on maintenance mode in the last few years. The ability to post updates on books / publications which don't have ISBN is the feature I miss the most :-(

Goodreads requires all books/shelves are publically-visible, which you may not want.
