nostr's protocol is also fairly unstructured compared to atproto. ive researched bluesky, farcaster, and nostr, and their cultural origins have definitely impacted how they have approached their designs.
There is no predicting what approaches will win, but those 3 are the current viable options I think.
FYI I am part of the crypto crowd myself, but I am a SWE looking at these systems, not a CT gambler, lol.
Oh, so what about the origins of Bluesky by the same founder(s) as Twitter ?
That alone gave me pause, as Twitter ended up as one of the most despicable platforms we have to suffer today (and yes, those issues are inherent in its nature, and long predate Musk buying it). But I guess that they might have learned from their mistakes this time ??
Dorsey is certainly focused on that realm
