IMO, the thing Goodreads has that nobody else is automatic updates from a Kindle. When I finish a book on my Kindle, Goodreads automatically tracks it. It doesn't seem possible for Story Graph or Bookwyrm or Librarything or any of these others to do that, which means I have to manually curate my list of books I've read and want to read. Right now, my process is this: 1) buy a book, 2) read it, 3) my friends can see that I read it and left a star rating. I think this makes a pretty hard barrier to entry in this market, because I read 99.9% of the time on my Kindle, and I'm lazy. :)
