If we only include modern technologies, then the Fediverse only has 12 million users.
But I also think that email, NNTP, finger, etc. should be considered part of the Fediverse.
If we consider *everything* federated as part of the Fediverse, then the Fediverse has billions of users.
In fact, it’s weird to think that anyone would not be part of the Fediverse.
@atomicpoet because as with all #MultiVendor / #MultiProvider & #OpenStandards, #ActivityPub and thus the #Fediverse, everyone can build Backends and Frontends and not rely on the whim of a commercialized #API...
