So I've found that there's two types of Star Wars podcasts that I've been seeking and unable to find. I'm assuming that they don't exist, but if they do by all means let me know.
1) A Star Wars literary podcast which features dialogue between two or more people -- or even a round table discussion -- about a particular book. I've seen some one-off episodes of podcasts, like the ForceCast had one for Darth Plagueis, but I am curious to see if there's one that exists specifically to go through each novel of the Expanded Universe, as well as perhaps comic arcs like Dark Empire, Crimson Empire, Dawn of the Jedi arcs, etc.
Here's an HP Lovecraft podcast that does precisely what I mean:
2) A Star Wars lore podcast, which features short episodes discussing particular topics of Star Wars lore, which would out of necessity need to be an EU podcast since what you see is what you get in the films. For instance, one episode might be about the origins of the Sith, or the Great Sith War, or Rogue Squadron, etc.
Here's an Elder Scrolls lore podcast that does precisely what I mean:
I'm thinking I might try my hand at #2. I think the common thread here, if those things don't exist and I'm not just ignorant of them, is that Expanded Universe specific SW podcasts aren't too common. Most Star Wars podcasts I've seen either cover SWTOR, or cover the current news about Star Wars -- which was true even before the Disney sequel trilogy stuff.
I find this strange because the amount of EU content would allow a podcast about the EU to continue in perpetuity, because you would never run out of content to discuss.
