Hello everyone! I just set up this new account?

Things seem pretty cool here on this "fediverse". What does that mean though, the "fediverse"? I hear it's using ActivityPub. Could anyone explain to me what that means? Thanks!

@cwebber It's actually Felineverse and CativityPub; created to spread cat images across the world on caturdays. However, when the final draft was saved a cat walked across the keyboard which introduced some spelling errors so here we are.
@joakimfors @cwebber actually the cat was the one sitting at the keyboard in the first place
