Some impressions from a few #librarytracking services.

#Goodreads. Pretty good integration with #Kindle, big community but in stagnation.
#LibraryThing. Good recommendations, terrible and old UI
#StoryGraph. So-so recommendations, not fast UI but have at least enough functionality
#Fable. Only on mobile devices (what?), an application just looks good but doesn't have a lot of necessary functions. Terrible customer support service...
