(Okay, it's not a book picture, but I can't do a blog post without a photo. . .)
I just discovered a site called Good Reads where you can set up an account and add friends (like Facebook or Ravelry) and review your books. I have only just set up my account and haven't had much time to explore it yet, but it looks like fun.
If you get on and want to friend me, I'm Mbarkle. (So far I have no friends and it makes me sad. . .)
