This is increasingly my experience on Twitter/X as well, that replies are just rubbish and there's very little scope for discovery/learning/asking questions. Still one of the saddest outcomes about how I've spent my time over the last decade!
Since I had such a large sample (nearly a hundred), I analyzed X comments by category.
47% said climate wasn't changing, I was lying, ignorant, or not really a scientist
15% said I was in it for the $
14% were insults

Sadly, with Musk as the owner, the platform has been ruined. He's corrupted the blue tick, allowed extreme right wingers & racists etc to thrive & ruined the ethos.
Even if somebody bought it, it would take a very long time to make it decent again.
