Everyone else uss "Mastodon" to refer to the whole fediverse, why not us?
At the risk of making everyone's worldviews crumble to dust:
This is pretty much why I have at least 80% of my Hubzilla followers. They've learned this from me, and they follow me so I can teach them more about the Fediverse that they don't know.
Let's forgo the blue pill that leaves you with the belief that all of the Fediverse is Mastodon and only Mastodon and wondering why some toots look weird and do stuff that Mastodon can't do, like strange-looking mentions or embedded links or over 500 characters. Let's go straight to the red pill that shows you how deep the rabbit hole commonly known as the Fediverse goes.

tl;dr ←
Pleroma is not Mastodon, nor is it a Mastodon fork. (In fact, it's 3½ weeks older than Mastodon.)
MissKey is not Mastodon, nor is it a Mastodon fork. (In fact, it's some 2 years older than Mastodon AFAIK.)
Akkoma is not Mastodon, nor is it a Mastodon fork. (It's a Pleroma fork.)
The project still known as
CalcKey is not Mastodon, nor is it a Mastodon fork. (It's a MissKey fork.)
Mitra is not Mastodon, nor is it a Mastodon fork.
And that's just the most important Twitter-like projects. All of them have features that people on Mastodon are craving for.
Friendica is "Facebook in the Fediverse". And six years older than Mastodon. It's from 2010. And it has outclassed Mastodon feature-wise without even breaking a sweat back in summer 2010 already when it was still named Mistpark.
Hubzilla is a combination of a whole lot of stuff in the Fediverse from Facebook to Google Cloud Services. It started out as a Friendica fork by Friendica's own creator. And it's four years older than Mastodon. From 2012. Built around a protocol designed by the same guy in 2011. And it offers loads and loads of features that Mastodon users couldn't possibly even dream of having on Mastodon plus lots of features that many are still waiting for Mastodon to offer. Hubzilla had nomadic identity in productive use a decade before Bluesky claimed to have invented the concept without ever having delivered.
Hubzilla is where I am.
(streams) is the code repository of, well, a fork of a fork... (it's complicated™) ...of a development version of Hubzilla. Still from the same creator. It's slimmed down again, dramatically so, it's mostly made for tinkerers which is why it doesn't have a defined brand, and it's said to be more modern than Hubzilla. After all, it was launched last year.
I'm still not done yet.
Pixelfed is Instagram in the Fediverse.
PeerTube is YouTube with a side of Twitch in the Fediverse.
Owncast is Twitch in the Fediverse.
Funkwhale is SoundCloud/Bandcamp/iTunes/... in the Fediverse, just without commercial mainstream artists. Or commercial artists, full stop.
Castopod: ditto, but specialising in podcasts.
Lemmy and
/kbin are Reddit or Hacker News in the Fediverse.
WriteFreely and
Plume are Medium in the Fediverse. Oh, and WordPress has a Fediverse plugin, too, that has just recently gone official.
BookWyrm is GoodReads in the Fediverse.
Mobilizon is Doodle in the Fediverse.
"But wait," you'll say, "aren't these all centralised and isolated silos all for themselves? What do they even have to do with Mastodon?"
Okay, here comes the really exciting shit. For one, every last one of these is at least as decentralised as Mastodon. Actually even more because they don't have lighthouse instances like mastodon.social where they try to railroad every last newcomer.
Besides, they all speak a common language. The same language that Mastodon speaks. ActivityPub.
What does that mean?
It means they're all connected to each other. Instances of all these are connected to instances of all the others. Like, you can be on Mastodon and communicate with people on, what, CalcKey or Hubzilla or use public forums on Friendica as if it's all Mastodon. Only that it isn't all Mastodon.
Again, I'm on Hubzilla. Over 90% of my followers are on Mastodon. The rest is all over the place. A growing number of CalcKey users, some of the few MissKey users whose first language isn't Japanese, Akkoma, Friendica, Hubzilla, (streams), FoundKey, even someone on /kbin has managed to follow me.
So if you come across a toot on Mastodon that does wicked shit that Mastodon toots shouldn't be able to do, maybe it isn't a toot, maybe it doesn't come from Mastodon after all.
