For the purposes of this thread LQG is defined in a pragmatic unrigorous way. Loop gravity is what loop gravitists do. That begs the question who are representative loop gravitists? Well it is a fuzzy set but I think we all have an idea who they are: people like Rovelli, Smolin, Freidel, sometimes-Baez, Bojowald... I am leaving some big names off to give you some to think of. And people who co-author a lot with those people. I would include Kowalski-Glikman and Magueijo even though strictly speaking they are involved in DSR, because that is a main focus of QG phenomenology. The important thing in talking about Loop Gravity is that it is a DIRECTION of several related lines of investigation. And it's important to have one's eyes open and focus on what Loop people ACTUALLY DO, rather than having some artificial construct in mind about what they were doing in 1996, or what is in some book. So this thread is an INTERPRETIVE thread, where I am going to give you my take on the current direction(s) of research in the community of people we think of as Loop Gravity people-----to a large extent it is simply those who attended the October LOOPS '05 conference or who are co-authoring with central people at that conference, but that would have to be qualified, so I will be somewhat flexible in what Loop-and-allied work I consider.
