I joined Goodreads today, if you'd like to friend me. I find it difficult to rate books or movies. I think my sons are right: I'm a tough grader. So you might want to bear that in mind if you look at my ratings.
If you are not familiar with GoodReads, it is a site for tracking what you've read, what you want to read, what your friends are reading, to read reviews, write reviews, all sorts of readerly goodness. Several of my friends have won free advanced copies of books, too.
