It is entirely possible that there are self-contained fandoms on umblr.
Umblr Staff have witnessed photo posts of innocuous objects, a 1991 Chevy Buick, for instance, with the following text comments;
"Imagine, though, if they’d had this."
"It would have been the perfect instrument!"
"But it still wouldn’t have saved them..."
In these posts, it is impossible to find what they or them refers to. There are no tags accompanying these posts, though the posts gain hundreds of notes from others who seem to know of the referent. How could members of the fandom discover these posts without tags?
If every fan was following every other fan, there would be no need for tags. Each user would be able to correctly assume that the person who posted the image of the 1981 Chevy Buick had been referring to the referent.
An outsider to the fandom would not understand. They might make the assumption that there is a book, movie, television series, or game, which is the common tie between the esoteric posts. But without substantial evidence of the media from which the fandom is born, the outsider would never have interest in uncovering the object of the fandom’s obsession.
What we believe to be even more likely, is that each member of the fandom follows only members of their fandom. Like a closed circuit, the fandom would operate within a separate pocket of umblr.
Where would this lead? Would entropy erode the object of the fandom’s obsession? Could a hideous mutation be brewing within the fandom? Would it be a 1971 Chevy Buick?
We have no control over our user base,
