Just signed up for GoodReads account.  I think I will get a lot of use out of it.  Just need to explore more.  My link is http://www.goodreads.com/friend/i?i=LTM2MjM2NzkwNzQ6NDI2.  I am not good at writing or submitting reviews so I doubt I will contribute a lot but just like the idea of being able to keep track of what I have read and want to read.
