Fediverse

The Fediverse, aka Fedi, or Mastodon, is a shitty email clone designed for people too gay for Twitter but too autistic for Tumblr with a long and boring history. Unlike Twitter, users are forced to host their own nodes, which can then federate with other larger, more cancerous instances, allowing for the greatest gay orgy you've ever seen.

Software

Like all Free and Open Sores software, nobody can agree on making one large, good software. Instead, everyone is split up between 300 unique broken pieces of shit that consume all your memory and CPU and have security vulnerabilities every other week.

GNU Social

The old grandpa of fedi software. This was the first instance that really kicked the concept into the rear end. A lot of the sovl and fun also happened here, if you want to call it that. This spawned lots of (formerly) famous instances, such as freezepeach, smugloli, shitposter.club (still alive), sealion club, and a million single user instances struggling to surpass a lifespan of 2 weeks.

Mastodon

If GNU social had too many Nazis for you, then comes over to Mastodon. Mastodon is not just a software, but a large and captivating political message. It decided to bring it's own standard into the mix called Activitypub, because OStatus or whatever GNU Social used wasn't retarded enough and, again, nobody in the open sores world can agree on a single standard. It's designed to rape your CPU beyond repair to it's desire as Gargron is too busy sucking furfag cock to optimize it.

Pretty much everyone that used Mastodon was a Gamian Migrant from Twitter. Many of these lusers refer to it as birds(h)ite despite being the core part of the problem. Of course, like all birds flocking, they bring their subcultures along with them and become befuddled with the idea that people can spam Nigger a ludicrous amount of times. This resulted in many "defederations", where instances reject all AP (activitypup) requests, completely walling them off, creating a circlejerk of homosexual monkeys flailing shit all over the walls.

It's gained quite a following ever since Elon Musk took over Twitter, with millions of users flocking to the same 2 instances because they don't know how Federation works and expect this to be another Twitter clone.

Pleroma

Pleroma was the final nail in the coffin for GNU Social, where some faggot named Lain created his own fedi software in a dogshit foreign language known as Elixir, making it impossible for outsiders without Autism to contribute. Ever since it's birth, essentially left GNU Social to rot in a pit for eternity until there were only 3 GS instances remaining. Instances like Shitposter.club and smugloli migrated to Pleroma, while the rest burned to the ashes never to be seen again.

Pleroma carried a lot of culture over from GNU Social, with various jokes like "cum", "suya", and "benis" and basically everything a toddler would mutter. Nobody who isn't mentally retarded actually laughs at these.

Rebased, formerly Soapbox

Soapbox is the last recognizable software, initially a fork of Pleroma created by a fat retarded vegan named Alex Gleason for the sole purpose of making a webshit frontend for Gab. Eventually, he broke off from Gab and made Soapbox a Mastodon frontend, and then eventually made his own Pleroma fork called Soapbox using his own Soapbox frontend.

The backend, "Rebased" has nothing of value to give for itself except for fixing some of the Pleroma shit faster and removing useless features. The frontend resembles modern Twitter aka it's shit.
