If you're into cold cases, you really should subscribe to the UnresolvedMysteries subreddit. You'll learn about new cases every day. It's also where you'll hear about the latest episodes of crime podcasts. Or used to. Something weird happened yesterday.
It started with this thread from the moderators, in which they implied all links to podcasts and blogs would be henceforth be relegated to a separate subreddit that nobody follows.
It didn't take long for their readership to say, "Uh... what?" The majority of commenters didn't support the change and when it began to sway toward other ideas, the post was "unstickied" and buried.
This is all very insider-baseball, I know.
But if you like Unresolved and you enjoy hearing about these podcasts, message the mods and let them know what you think.
