Mastodon (Fediverse) is currently more diverse for sure, but back in 2009 it looked very much like nostr does today: just swap the word "bitcoin" with "opensource". I love the fediverse for its fauna and flora, but i think it is ill equipped for the modern internet. It only decentralizes the value we create on it (posts, social graph) while it fully centralizes identity (single point of failure to access the network) The natively cryptographic nature of nostr is a lot more resilient. The nostr network is permissionless, but relays are not. Which leads me to deduce that it is possible to build far tighter and safer communities on this platform, without tying anyone up to an admin. Since it's equally confusing to explain fediverse than it is explaining nostr, i have entirely given up on trying to grow the fediverse and shifted my attention to nostr. And i say this as the maintainer of 5 different activitypub thingies. Which is also a testimony of the shortcomings of mastodon: you need a new account for every format...
