The first site I've discovered is this:
http://happy-booker.blogspot.com/
I'd like to keep an eye out for her next year's book challenge, if there is one, at http://evie-bookish.blogspot.com/2011/11/2012-tbr-pile-reading-challenge-sign.html
Some days I play with the idea that the year I turn oh 80 I'll do a book blog too. Too busy right now and probably for decades to come...
I see one could practice foreign languages at that general site too!
