I apparently didn't mention it here, but I've started to use
my read shelf:
John's book recommendations, liked quotes, book clubs, book trivia, book lists (read shelf)
I like it pretty well already, but according to a friend who recommended it, it gets better if you have friends using it, so you can see what they're reading. I don't expect anyone to be particularly interested in what I'm reading since I am generally not reading anything that everyone else has read years ago but if any of you are GoodReads members, I'd be interested to see what you're reading/have read.
