I listen to all sorts of podcasts, some of them in a related "family" of comic book podcasts. They consist of guys about my age going over the comics they loved from the Silver, Bronze, and Whatever 80's age.

This lady is the biggest Batgirl fan in the world, and she discusses everything from her first appearance in 1967 up until she becomes Oracle (stops there). She catalogs all her TV and movie appearances, comic appearances, etc.
She's done over 100 episodes dating back to 2009:
