Do you every listen to podcasts?  I'm trying to learn about them and not seem so archaic.
I sure do! Though, I often have to be kind of careful when listening to them while not at home. Since they are streamed, they can use a lot of data. 
I'm struggling to wrap my head around them.  Aren't they just like listening to a radio talk show?
Not quite; they come out on a subscription like basis. So, a lot of the time, the podcast creator will put one out every week, or every month, et cetera. 
Oh.  Hum.  So more like an informative YouTube subscription, but audio only?
Yeah! There's even software that can automate downloading some new podcasts, which can help a lot when one is trying to listen to them on-the-go. 
What types do you listen to?
I enjoy comedy podcasts, personally. I find them very intriguing whenever I take long drives. I personally like to stream mine off of Spotify.
