Possible origin of the term "The Fediverse" as a term
I'm going from memory, so not sure it's all correct, but usage of the word "Fediverse" early on was typically used with the "!", as a cross-instance general posting group (Fediverse being the "who", in this case "everybody") and was often combined with a subject/topic group (the "what", in the case of !tzag(*), a greeting, which optionally had tags to other subjects or groups.
