The Loops conference held every two years, or so, gives us a good window on what the active lines of development are, what the organizers consider the main issues to be addressed and who they see as leaders in the various LQG research areas. LQG is a research community rather than a single "official" formulation of a single agreed-on theory (that would be kind of ridiculous ) and there are in the community a number of active productive lines of development. It's the business of conference organizers to identify these and get them in focus in their list of PLENARY SPEAKERS and in their schedule of PANEL DISCUSSIONS. Plenary speakers are the ones who usually speak in the morning sessions and present their talks to the whole conference (which might be 300 people in the main hall). Then in the afternoon the organizers let people divide up into 3, possibly more, "parallel sessions" run in smaller rooms. So there is time for many more parallel talks. So you can see how this year's Loops 2015 might provide a kind of snapshot of who the people are and what the promising developments are in the LQG community. Fortunately the list of plenary speakers has been posted, and also the list of 4 panel discussions (one on each of four evenings M T Th F.) It's worth studying, if you are interested in learning about LQG.
