Goodreads is only good (eh, decent?) as a database of books you've read. All the other functionality is pointless and or broken. The recommendation system is a joke and is obviously used to promote nonsense instead of giving you personalised recommendations.
I found it often did what social media is partly designed to do—-make one insecure about whatever the focus is. You’re either not reading the right books, not analyzing and commenting enough on books you read for enjoyment, or not reading enough regardless of your actual place on those subjective spectrums. All their to make you feed the social media machine with your free labor in the form of analysis/reviews or whatever.
