I subscribe to 20+ podcasts, most which have more than 1 new episode a week. I find it really hard to listen to everything I want to, and now not having a long commute to work compounds this.
I find it very difficult to listen to spoken audio whilst trying to concentrate on something else otherwise I could probably listen to much more than I do.
Most of my podcast listening is via BeyondPod for Android due to it having the ability to auto download new episodes of shows.
I always prioritise WOR about other audio due to it being time sensitive, but then I just listen to something that peaks my interest. For example, this week it was the SuperShow with Parv, Will, Johnny and Steve.
I am just interested in others listening habits such as when/where they listen, how much content to they listen to etc.
Edit: I find Joe Gagne's Podmass articles a great help to decide what to listen to also.
