Everything has a fandom, no matter how small!

Is this not true anymore? Or was it never true and I am idealizing the past?

Fandom is spread out over many social media platforms and different LJ clones. I hear whispers of lost tribes still using InsaneJournal. Many of the platforms we use are terrible for conversations, challenges or even fans playing silly games among themselves. Changes to Tumblr tag tracking seemed to be the nail in the coffin of the few small fandoms I was in.

What do you think? Are small fandoms pretty much a relic of earlier versions of the internet?
