Owner of an 80 GB iPod classic, with 361 unplayed podcasts, totalling 11.7 days:
• Escape Pod (caught up)
• Mr. Diety (faded, probably not coming back; according to Brian Keith Dalton, it IS coming back for a third season, though no date has been set yet)
• New Yorker: Fiction (just subscribed last week, 19 unplayed)
• NPR: Story of the Day (caught up; I delete uninteresting titles without listening)
• NPR: Wait Wait Don't Tell Me (caught up)
• Podcastle (12 unplayed caught up)
• PRI: Selected Shorts ([18 unplayed)
• Spider on the Web (48 unplayed)
• Starship Sofa (77 unplayed) - I got into this one because they posted Spider Robinson reading his "Melancholy Elephants", but I really don't like the host's voice, so this one may go.
• Stranger Things TV (caught up) - I was impressed with the first few, but this last one (3 parts) was a poor story. The production quality is great, but if the story is boring, who cares?
• This American Life (13 unplayed) - I cull this one like NPR SoTD; anything with a boring title gets deleted unplayed.
• Variant Frequencies (82 unplayed) - I subscribed because it was recommended, but haven't listened yet.
• X Minus One (80 unplayed) - Same as VF
I keep up with Escape Pod and both NPRs, and once I get caught up with Podcastle, I'll keep up with it as well.
I keep audiobooks separate, even if they were acquired as podcasts (e.g. Playing for Keeps). I had read all of the first six Harry Potter books, the last four almost immediately after they were released, but never seemed to find time to get into book seven. When I realized I was spending a lot more time in my car than before, I bought the audiobook on CDs, ripped it to mp3s and loaded it to my iPod. It was so much more satisfying, I found, though before the movies come out, I'll read the book (again?). I, too, love Mur Lafferty's stories, as well as when she reads stories by other authors for EP or PC.
Edit: changed Mr. Deity and Podcastle
