This. When people talk about break-ups, you learn something about human nature like people's different attachment styles and each person's unique emotional vulnerabilities and their resilience in spite of it. When people talk about their careers and work stories and when you really listen, you learn about what people truly value (getting money vs. an academic pursuit, integrity vs. personal expediency); with travel stories, there is no character arc, more like a pastiche, a camera pan of the landscape they traveled to.
