Smolin - Motl Cage Match
In a previous post I mentioned the Nicolai and Peeters critique of Loop Quantum Gravity, and mentioned discussion of it by Peter Woit and Lubos Motl. Lee Smolin has a response on Peter's Blog at here, here and here. Lubos has posted a pont by point (sentence by sentence) rejoinder on his blog here.
Lubos argues that GR is just special relativity with gravitons - a bit hard for me to accept, but I don't want to comment too much on the discussion, most of which I don't understand. Lubos would have more credibility with me if he didn't throw in stuff like this:

The only way how you can get a different result is that you actually accidentally hit a completely consistent theory of quantum gravity - but it seems impossible because you can't really get string theory out of LQG.and if his judgement was a bit better on less esoteric matters.
