Podcasts are radio on demand. They offer all the variety that radio does, or did, and more. They can offer the quality of a good commercial radio show, or the quality of a rotting potato, or anything in between. It’s up to you to find something you like. There’s so much out there that there is probably something you’ll like.
So many of these comments talk as though “podcast” implies news or commentary and that’s it. Did I stumble into an alternate universe? I know those exist (news and commentary podcasts exist, that is), but there’s so much more. The closest I get are news-related comedy shows like Wait Wait or the BBC’s Now Show. I’m always on the lookout for the next episode of Welcome to Night Vale, and on the rare occasions that there’s a new Hardcore History, it’s a real treat. If I run out of something new, I love to listen to an episode or two of the old Dragnet radio series and get immersed in 1950’s Los Angeles.
Podcasts are inferior to text or video? That’s like saying that cheese is inferior to the Central Limit Theorem. The comparison doesn’t even make sense.
I basically can’t listen to podcasts without something physical to do. If I’m idle and trying to listen, I’ll start reading something at the same time and miss half the show. But while I’m out for a walk or doing yard work or cooking or on a long drive? They’re the best! Text or video aren’t sensible there. The only competition would be radio (or, ugh, my own thoughts), where the comparison is just like the comparison between live TV and video on demand.
