To use an analogy, think about jokes. We all have friends who are better joke tellers than we are. Whenever they tell a joke the room bursts out laughing. But jokes also vary. Some jokes are so funny that it doesn’t matter who tells them. Everyone laughs even if the person sharing the joke isn’t all that funny. Contagious content is like that—so inherently viral that it spreads regardless of who is doing the talking.
