Can't tell your post is sarcastic or not. Good reads is a valuable resource, especially for avid readers - without it I wouldn't have read as many good books as I did.
Maybe the reviews were better, but I think in general the trend of trying to replace discussing things with people with an automated service or social network leads to a poorer result. I read a ton and have never used a recommendation tool to find them, I just read books, go to bookstores and talk to people about them.
