I've noticed if you follow the "Indie Hackers" on X then you will get lots of self promotion (ie. "My startup just hit $X/MRR!!, here's how I did it: substack.com...."). On the other hand there are other places like "Finance X" or "Sports X" where you get deep dives about the state of that space from various people.
Moving away from X/Twitter, there's tons of "authentic" content you can find on Youtube, a recent favorite of mine has been watching Peter Santenello[1]. He could be considered a journalist and his whole thing is just going into random communities and talking to people. I especially enjoyed his series about Appalachia and the Hasidic Jewish community in Brooklyn.
