Of course, Joanna's blog is just one of many that review great books for young people and adults. If you're especially looking for teachers to follow who are dedicated to instilling a love of reading, I suggest that you start with:
Sarah Mulhern Gross, contributor at The Learning Network at the New York Times, who blogs at The Reading Zone, and is @thereadingzone on Twitter, and
Donalyn Miller, author of The Book Whisperer, whose Twitter ID is @donalynbooks. Her Facebook page is also called The Book Whisperer.
I'm looking forward to reading this book, and perhaps seeing the movie, which is currently in pre-production.
