I shouldn't say I do because string is not my area of research, but I can say I have more than average knowledge on string theory than most of non-stringy graduate students.

Instanton, in the other thread you recommended a LivingReview
survey article of Loop Quantum Gravity-----as a "good review but not for the faint-hearted" or some such phrase. This is a strong recommendations. Is this the article you meant?
http://www.livingreviews.org/Articles/Volume1/1998-1rovelli/RovelliLivrev.html
It is a 1998 survey of LQG by Rovelli.
There is no comparable thing by Thiemann

Can you say the same for Loop Quantum Gravity?
I hope very much that you can, and that your knowledge of LQG is more than that of the average non-loopy grad student!
If so, then I have hopes of your helping me to compare the merits of these two main approaches to the quantum theory of gravity.

Actually i am more interested by far in lQG than in strings. It is not that i deny the merits of string, but i it needs too many asupmtions about things we have no any evidence, extra dimensios the main one.
Instead LQG is based in stated physics. Also i like the level of mathe rigourosit the LQG people works, String theoriest are a too crude extension of path integral QFT methods without greater justification.
String theory is a theoretical framework in physics that attempts to explain the fundamental nature of matter and the forces of the universe. It proposes that particles, such as electrons and quarks, are not actually point-like objects, but rather tiny strings that vibrate at different frequencies.
String theory is often seen as a unifying theory, as it attempts to reconcile the two major theories in physics - general relativity and quantum mechanics. It also incorporates concepts from other areas of physics, such as supersymmetry and extra dimensions.
As a theoretical framework, string theory cannot be proven in the traditional sense. However, it can be tested through experiments and observations that could provide evidence for its validity. Currently, there is no experimental evidence for string theory, but it is an active area of research.
String theory is a highly complex and mathematical theory, making it challenging for many individuals to understand. It requires a strong foundation in physics and mathematics, and even then, it can be difficult to grasp due to its abstract nature.
If string theory is proven to be a valid description of the universe, it could have significant implications for our understanding of the fundamental laws of nature. It could also potentially lead to advancements in technology and our ability to manipulate the physical world.
