What I like about goodreads is that it has reviews (not ratings, I noticed that those are becoming gamed a lot), description, quickly identifiable genre of book (shelves) and link to other books by the author. That's about it. I personally don't like posting reviews, especially if the book is bad, because it feels rather mean towards author and I know few authors whose first books were pretty terrible but they eventually improved a lot.
I would like a app where I could add my notes on a book, could easily see that I already read book by an author and also add note to this author (for instance "avoid", "read if nothing better available", "read only later books", "read everything except series Z" etc.) and it would have appropriate notifications. I don't need recommendation engine, some kind of search based on genre, tags, popularity and rating would be enough.
