Give yourself some credit! Your human-level intelligence is only using about 20W. The other 80 is for the meat robot it has to pilot to get stuff done.

I think the main one is that Nostr is supposed to be really simple, and derive some security/privacy from that simplicity. Whereas ATProto and ActivityPub store and forward content so that each rely has a copy, on Nostr nodes the messages are all ephemeral. So it has something of a following with crypto bros and privacy enthusiasts. With nostr IDs are also based on public/private keys unlike ATProto/ActivityPub that use a username@instancename scheme, so signing and identifying content that belongs to a user is easier and more guaranteed to be correct, and your username isn't tied to any specific server "instance"
I kinda agree Twitter was born of a more innocent age, and he was just a tech kid with a good enough pitch to get Silicon Valley VC. The problem is that he did little to rein in powers that were purposely using the platform for social manipulation. Then -- when he already knew better -- he went and started Bluesky, which he specifically said was going to counteract all of Twitter's deficiencies, but capitalism got the better of him, so to make the platform attractive to VCs, advertisers, whatever, his team started to ditch what made Bluesky unique in favor of business tools to help it make money. Business is gonna business, it's not 100% his fault, but I can't imagine what will change a 3rd time around.
Maybe that was the case 20 years ago, but today there native son Gen-X and Millennial shits are voting just as hard R as the old folks used to. I’ve been here the whole time and watched the whole state transition from “haha” dumb to “dude, wtf?” dumb.
