If you love reading books (including comic books), then goodreads is the site for you. goodreads is a Free site where book lovers can join to find out about new books or older books you might of been thinking of reading. You can also review and rate a book or read other members reviews. You can also set up your own library which includes books you are currently reading, have read and plan to read.
Like any other social networking site you can meet new people and form or join groups. What I like about goodreads is there is a group for everyone from "Rory Gilmore Book Lovers" to "Fans of Amish Fiction". goodreads is truly a book lovers paradise.
