allow me to criticize the state of the fediverse as much as love it:
- tiny brain: mega-node such as mastodon.social oh dang it we've reinvented twitter
- regular brain: I'll just choose an instance off of joinmastodon.org oh dang it got shut down everything I love is lost
- galaxy brain: I'll self host fedi software oh god this is hard I'm afraid to upgrade
- universe brain: we need to merge the fediverse with p2p network designs so a node going down isn't catastrophic
btw, some of the "gaps" that were left in the activitypub spec were intentionally there to enable this to exist https://github.com/WebOfTrustInfo/rebooting-the-web-of-trust-fall2017/blob/master/final-documents/activitypub-decentralized-distributed.md
for example "why didn't activitypub require https as the only valid uri scheme / protocol"
well, the solution to the "content surviving when nodes go down" may rely on the fact that this was left open: https://github.com/WebOfTrustInfo/rwot7/blob/master/topics-and-advance-readings/magenc.md
@elfprince13 some people are trying to make E2EE stuff for AP, I think @soatok did a writeup with some ideas
