Main audiences I see:

Nostr devs and people talking about how Nostr is going to take over the world but zero effort into retaining new users.

Bitcoiners talking about bitcoin and shitcoins. Don’t know why though. If everyone already knows what you have to say the only reason to say it is to engagement farm. And why talk about shitcoins if shitcoiners are not here? Again - engagement farming, dopamine farming.
