Eh, reddit really isn’t much better in this department. It’s not uncommon for multiple subs to exist for the same userbase (r/memes vs r/dankmemes, r/christian vs r/truechristian). Over time users figure out which is which, which is the main one, and which is for them

Gonna be honest I don’t really understand the Fediverse yet but I’m here cuz it feels cool and reddit kind of annoys me these days
