5 years ago you could think of CDT and AsymSafe as part of a group of approaches called "Loop and allied QG". The numbers of people were so small it seemed like a single non-string QG community. Rovelli convened a Loop-and-friends Nonperturbative QG workshop at Marseille in the spring of 2004. Some 50-60 people participated. Loll included. So CDT was part of that first conference. The next year both Loll and Martin Reuter gave invited talks at Loops 2005 Potsdam. Both CDT and AsymSafe were again represented at Loops 2007. Now CDT has grown and is appearing as a potential rival to Loop. 5 years ago CDT was only being done by Renate Loll's group at Utrecht. Now the CDT computer work is being done in at least two other places, Perimeter and UC Davis. People show up at conferences from places like Poland and Iceland to give CDT papers. Loll administers a large grant from the ESF (european science foundation) able to support postdoc contracts, meetings, workshops etc. AsymSafe is also appearing as a potential rival. Important landmarks were the talk at CERN by Steven Weinberg and the organization of the Perimeter conference to be held in November. Horava QG is another 4D approach that is getting a lot of attention. Herbert Hamber is making a strong pitch for massive computer calculations along Lattice QCD lines to implement his version of Regge QG. Carlo Rovelli is this week presenting a "new look" LQG, and the abstract stresses its analogy with Lattice QCD---and mentions renormalization. You may want to add others to the list of contenders. Any of these could become a star or premier successor to string. All can be seen as jockeying for position---scuffling for a place in the sunlight that has opened up. What physics differences do you see? What are the strong/weak points? Sometimes one cannot tell if some feature is an advantage or disadvantage, it is just a difference. These distinctive features should still be pointed out. All these approaches seem to echo the themes of renormalization, and continuity with the tried and true, the "good old" (as Weinberg put it) Quantum Field Theory. Several if not all the recent presentations refer at some point to the success of Lattice QCD.
