Recently, I am very interested in Loop Quantum Gravity. But I hope I can know more about the recent development of Loop Quantum Gravity. I mean the development from 2000 to 2011. Any conceptual or practical or technical development in this realm? Further more, I do not know the relationship between Carlo Rovelli's Quantum Gravity and Thomas Thiemann's Modern Canonical Quantum General Relativity. They looks so different. Thank you very much.
