I find Twitter conversations are just as shallow unfortunately. I do follow a couple of people there - Benedict Evans and patio11, but comments on their tweets aren't any better.
How do you find those smaller accounts though? When you look by topic you tend to get tweets from popular influencers. And I may sound lazy but I don't like the idea of doomscrolling through Twitter just to find the right person.
Depends on what kind of community you are looking for, for me it's mostly IndieHackers and HN so I often click through profiles on HN comments or if there's a blog post shared on a personal blog I look for their Twitter account there.
After you built up a few interesting accounts finding more accounts via Twitter is easier and less noisy.
