It definitely took me a bit to wrap my head around the fediverse, but the presence of a “main” site (in this case, Lemmy.world, or in Mastodon’s Mastodon.social) has made it pretty easy for me. I hate that crypto nerds took “web3.0” because I think, in most ways, the true inter-operability of social networks is the next “web2.0”-tier step that the internet can take.
