I don't think I'd pay for social-media-via-nostr. SN has some threshold of quality. Nostr may be uncensored, but most content is of brainrot quality. Nostr doesn't fix social media, just like Bitmessage and similar stuff doesn't fix free speech. Uncensored usually just means more space for crazies.

For me nostr fixed social media. I just don't use global feeds or anything like it. Curating my follows and having it as a default and exclusive feed is all that I ever needed from social media. X account long gone. Fb suspended and due to be deleted. I basically forgot about Instagram.
