Host Ben Brock Johnson and producer Quincy Walters go to an historic Boston cemetery to try out findagrave.com — a volunteer-generated database of millions of graves throughout the world.

At the cemetery, Ben and Quincy have a hard time finding anyone who's ever heard of the site that's been around since 1995. Despite this, Quincy makes the argument that Find a Grave is one of the first social media sites that doesn't get the respect it deserves. "But how is it social media if no one knows about it?" Ben asks.

Then the pair encounter a veteran user of the site. After that, they get ahold of the guy who started Find a Grave. Does he think Find a Grave is social media? Find out in this episode of Endless Thread. 

Back in 2013, the sand dunes of Michigan City, Indiana swallowed a six-year-old boy. It took rescuers nearly 4 hours to dig him out of 12 feet of sand. It was a phenomenon that scientists hadn't studied in-depth. But Facebook recreational naturalists were on the case.

In this episode of Endless Thread, producer Grace Tatter and host Ben Brock Johnson go down an internet rabbit hole and bring bring us an explanation of what happened, the coexistence of miracles and science and even the including the six-year-old boy who's now an adult.

"We're pro-portal and we're pro- tree hole," Ben says. "Basically anywhere there's space, we want to explore it."

Back in 2004, NBC’s 'To Catch a Predator' captivated millions of viewers as it followed a vigilante group called Perverted Justice, which has a goal to thwart pedophiles searching the internet for minors. Adult volunteers go online to pose as minors in order to, well, catch predators. Three years later, amid its growing popularity, it came to an end. But nearly two decades later, it's inspired a genre of influencers who have tried to fill the void.

The popular YouTube channel Lofi Girl provides a 24/7 livestream of chill beats to relax and study.

The cover art for the 1976 paperback edition of Madeleine L'Engle's classic sci-fi/fantasy novel "A Wrinkle in Time" — featuring a rainbow-winged centaur and a green, glowering, red-eyed face — is iconic. And yet, for nearly 50 years, no one has known who illustrated it. Well, not NO ONE. Not anymore... Endless Thread cracks the case!

As of late, Endless Thread co-host Ben Brock Johnson has been obsessed with a rock in Wyoming, a lot like the protagonist of Close Encounters of the Third Kind. But you won't find Ben in the kitchen, making a replica of the rock out of mud and chicken wire. Instead you'll find him and co-host Amory Sivertson in this episode, traversing Reddit and TikTok and YouTube and Wyoming to find out why hundreds of thousands of people have been drawn to a monolith that has so many names and meanings.

"To avoid crowds, visit areas that are less crowded." These comically obvious, wise words come from the Twitter account — ahem, X account — of the National Park Service, who has been hitting it out of the park lately (get it?) with its social media content and reaping viral rewards. Who is behind this material? And why has a more than hundred year old government agency chosen to let its hair down on social media? 

Amory and Ben talk to the National Park Service's lone social media ranger, Matt Turner, and to Sarah Southerland from the Oklahoma Department of Wildlife Conservation, whose delightfully outrageous social media presence has captured the hearts and funny bones of hundreds of thousands of people.
