You listen to a great podcast at work, but it's on someone else's phone. It really sticks with you, and you want to tell other people about it later. The only problem is that you have no idea how to find it. You don't know the name of the host, the show or the episode. You do not know when it was recorded or when it aired. For all you know, it could be from last Tuesday or from five years ago. What you do remember is what the podcast was about, the questions it raised or the ideas you want to revisit. You know how the content impacted you, and you have a fundamental understanding of the topics it covered.
