Smolin looks to me like he has about halfdozen QG-related things under investigation right now at Perimeter Institute---maybe a halfdozen main quantum gravity issues, or lines of investigation. I know they do other kinds of research besides QG, but now I am just looking at the one sector. The complexity is getting to be exciting and (without resorting to a checklist like this) a bit hard to follow. 1. Race to testability 2. DSR Soccerball 3. Dynamical triangulations 4. Immirzi parameter 5. Kodama state 6. Extended diffeomorphisms (if not already, will be working on this one) I will discuss each ring of the circus, inviting comment as well. But first I want to list some recent papers, at least one dealing with each issue. The paper can serve to illustrate the issue without my having to explain. I am not including CNS (cosmic natural selection) which is Smolin's scientifically testable multiverse theory. We already have a thread on that and CNS is not logically a part of Loop Gravity. It is its own separate theory. One can think of it as a "sideshow" to the main circus.
