I just spent a few minutes updating my podcast subscriptions - I haven't really listened to podcasts for several months, and want to get back into more curated audio presentations, as opposed to the relentless randomness of Shuffle Mode music playlists.
I decided my previous set of subscriptions were essentially a self constructed echo chamber. I had subscribed to several edu-podcasts, all talking about various interpretations of the same issues. I need to break out of the echo chamber, so I unsubscribed from most of them (sorry - nothing personal). I added several music related podcasts, and a couple talk radio shows.
I'm not sure when I'll have a chance to listen to them all, but I'm going to try. Perhaps as good background distraction while writing...
