Fay,
	You linked to an article EndtimesHeadlines.org.
btw - they have a very exciting and informative podcast, that goes along with their title, "EndtimesHeadlines".
Since my trip to/from work is about 1½ hours, each way, I listen to various different podcasts.
But after I read about grad students listening to lectures at 2x speed, I started listening to podcasts at 1.5x speed.
Then when I finally got used to listening at that speed, I moved to 2x speed.
It took longer to get used to 2x, but like those grad students said, you eventually get used to listening comprehensively at that speed.
Therefore, I'm able to listen to twice as many podcasts in a year, than I did before.
