Any suggestions for more along these lines?
podcastle is the fantasy cousin to escapepod. starship excelsior if you like scifi audio dramas, Prometheus radio theatre as well, and a bit of random everything (well after it went daily) is voice of free planet x, it even comes with the podcasts aliens you will meet, fables of the flying city, and Jared and steeve like comics included in the feed.
If the CBC podcasts aren't regionally restricted, a few that I find worth listening to are:
- Vinyl Cafe: light stories
- Ideas: hour-long looks into things like Science of Shakespeare, the Sharing Economy, a visit to Shackleton's grave, etc
- Spark: technology & culture
I listen to those, along with FAIF and Serial. Will checkout out some of the others in your list shortly.
