Just got passed an invitation to yet another social networking site called Goodreads. My first impression is that it's Last.FM for books.
There's a database of books I can browse or search through and rate on a scale of one to five stars. So far I've made it through 229 of all the books I've ever read. How did I have time? Rafe Needleman asked me to write this blog posting, and therefore it became "work".
But it didn't take that long to rate a bunch of books. I perused the overall lists of most popular and least popular, then perused the lists of a few of my friends. That last was annoying, because when you view a friend's list you see their rating and can't rate the book yourself. I had to click through to the book to rate it.
You can also add books to shelves. The default is to add it to a "read" shelf" but I also added the books I'm currently reading to the "currently reading" shelf. And I even added a book to the "to-read" shelf.
