Podcast Management

I am currently subscribed to about 25 podcasts, each with either daily, bi-weekly, or weekly release. I benefit from listening to them all, but I feel like I don’t have enough free time to do so. Mostly I do my listening as I walk around campus or do odd things around the house, but often I need to focus on written material which prevents me from simultaneously understanding the podcasts.

Does anyone have any suggestions about how to digest lots podcasts in a very structured and efficient manner? Is 25 podcasts a lot, or not much at all? Anything you have to say about this subject will interest me.

Thanks!
