It’s a social network like nostr, except with more users and more schizos.

So you know how there are Twitter clones Gab, Truth Social, Parler, etc? Well, imagine a million Twitter clones that are designed to interact with each other, much like email. It’s anti-jannying like nostr, but with a slightly different structure.

Good question. It’s a bunch of servers that are connected together. A sort of decentralized microblogging. According to Wikipedia, Mastodon is part of it (under fediverse software packages). Sounds vague tbh
