'old internet' has an appeal to both young and old. Not that anyone listens to me, but bitchat forum (styles as message boards of old) fork would potentially be very popular too. Imo imo imo

Also what is like irc now. Nostr-as-microblogging is like farcaster, is like twitter, is like Bluesky is like etc etc etc. not much novelty aspect to that, not a very 'shareable down the pub' conversation point here

Bitchat (afaik) has no marketing beyond jack's tweets (you could pretty much say the same for nostrmicroblogs). But it is probably getting a lot word of mouth promotion.
