*When someone asks me what's the fediverse*
"You see, it's like our oceans. We've got the Pacific, Artic, Indian, but all of them are just filled with the same water.
We've got Mastodon, Pleroma, Pixelfed, they all are connected the same way, but contains different sorts of species, different currents, different names at different places.
you don't know where exactly each ocean ends, but everything is filled with the same lovely people, mate"
