I mostly pay attention to posts asking for recommendations just in case there's a little gem of a podcast made out of passion.
Once or twice a year I try one of those I hear ads for and end up deleting them soon after.

One of these gems if you're into it is The History in the Bible Podcast. From its website:

...a layman's guide to a century and more of research into the Biblical texts and the archaeological evidence behind them.

I found it surprisingly interesting and some of Gary's sarcastic jabs made me chuckle from time to time.
