+1 on the AMAs. And while doing them with "big" names (Galen, Jager, Flanagan, Coburn, Salazar, Wetmore, etc) would be fun, access to folks at that level is limited, and coverage of them is substantial (even if it's not often the type that the typical LetsRun reader would want).
I feel like one of the things that makes this site great is how it goes deep, and the AMAs could be a cool, regular (weekly. . . or even more often?) feature if they focused on folks who are less in the limelight (coaches like Drew Wartenburg and Robert Gary; runners like Louis Serafini, Ford Palmer, Katja Goldring, and Sara Vaughn; agents, race directors and meet directors), but are still key players in our sport--and are also a little more accessible (and possibly relatable to the average LetsRun reader).
