I joined Goodreads tonight.
I ranked 748 books in one sitting, and I feel like I've just barely scratched the surface. I wonder how many thousands of books I've read in my life. I certainly feel fortunate to have had access to so many!
I am also pleased with the wide variety that I'm finding even in this cursory first search. I'm ranking everything from Hobbes' Leviathan to Westerfeld's Leviathan to Calvin and Hobbes.
Are any of you on Goodreads? I'd love to become a "friend" there as well -- as soon as I figure out how. :)
Update: okay, my list is now at 968 books ranked, and that's all I'm going to do for tonight. :P
