Since Mastodon saw its initial popularity circa 2017, I've noticed that most users and those reporting on it either don't think about the Fediverse as anything more than Mastodon, or treat its history as beginning with Eugen Rochko and the beginning of Mastodon. In fact, Mastodon is the latest in a long line of federated social networks going at least back to Identi.ca, and though I wasn't around for all of it, I find this history pretty interesting.
