The "current thing" on nostr is ephemeral, limited to about an hour of organic, authentic attention. Then it retreats into the mindshare of a handful of people that actually give a shit.
On Twitter, there is an algorithm that is designed to get you upset to the point you engage. So it is constantly in your face, saying "HEY REMEMBER THAT CURRENT THING YOU REALLY CARE ABOUT!? THERE ARE SOME ASSHOLES OVER THERE THAT HATE/LOVE CURRENT THING AND YOU NEED TO GO DEFEND/DESTROY IT FOR THE GOOD OF YOUR TRIBE"
