There is a detailed book on fandom (it's about another show), that's so in-depth that I urge fans to take a look at it on Amazon. I'm not advocating buying it. But Chapter 17, "The Reciprocal Relationship: The Producer And The Fans" will resonate with so many fans I had to pimp looking at it. Mods, take this post down if it is inappropriate.
