Episode Description
Abigail Vacca of Global Treasures
---
SUMMARYSebastian sits down with Abigail Vacca, creator and host of Global Treasures — a podcast exploring the history, legends, and culture behind UNESCO World Heritage Sites. Abigail shares how a childhood bucket list rediscovered during pandemic stress-cleaning led her to fill a surprising gap in the podcasting world. She opens up about her meticulous research process, how the show has reshaped her worldview (including her eating habits), and what it really means to be a responsible storyteller when covering places as fragile as they are fascinating. The conversation also touches on content strategy, the video-vs-audio podcasting debate, parasocial relationships with listeners, and what Abigail wishes someone would invent to make her one-woman operation a little easier.
