When Kaitlin Prest was first recording her podcast, born from a “radical anarchist radio station” in Montreal, it wasn’t called “The Heart.” Instead, she called it “AudioSmut.” In the eight years since, Kaitlin has changed more than the name of the podcast — the show has moved to New York, and Radiotopia brought it under the company’s radio family. But the podcast mission remains: To tell real stories of relationships and intimacy.
