I was reading an old issue of Time magazine yesterday (December 2007), and it featured the best websites of 2007. At number 5 was Goodreads.com ---> http://www.goodreads.com/
a wonderful place for book lovers!
I joined today (it's free, quick, and easy), and I hope that you join too (please oh please). We can share our opinion on books, explore each other's reading lists (as well as everyone else on the world wide web), and even start our own book club. Get real book reviews from real people... like myself. Check it out! You won't be disappointed.
