Do you have an account on Goodreads? Do you spend much time on there? Are you interested in adding new friends on Goodreads?
I love Goodreads! Goodreads and Facebook are the only sites I make sure to check every single day.
Not yet, but thanks to your question i will be checking it out later.
If you have many books, want to keep track of them, want to have suggestions, etc., it's a great site.
Having read over 3000 books, I do keep a list of most of the books I have read, in order to not re-read books unintentionally.
I asked my sister, who is also an avid reder, about the site, and she said she signed up, and then got a ton of emails and spam, so you deleted her account there.
