I don't know what this says about me, but two of my current favourite podcasts are ones that offer a brief glimpse into the lives of anonymous strangers. They are Where Are You Going? and Strangers On A Bench.
(I also used to like Beautiful Anonymous, but it's a bit too high-energy and sweary for me.)
