The mobile app is horrible. It's a webview or something, and works like total crap on old devices. If you open a notification for a group discussion post, it tells you what the title of the discussion is--but not what group it's for.

As much as possible, I find myself interacting with Goodreads through calibre plugins; I've got a library with zero actual book files that contains an entry for every book in my library, and I mainly use that to browse my collection. Since syncing that list takes so long, my actual calibre libraries are also synced to Goodreads, as that's where I actually make my changes.

With Library thing's recent removal of library limits, I'm thinking more and more about abandoning Goodreads--except I don't know if there's a calibre plugin for PT, and I've spent so much time adding and updating book records for items in my goodreads library, which would have to be redone for LT.
