I have former academic coworkers who use it to promote their publications etc. It's an odd thing because their (very left) politics definitely don't belong on twitter anymore. The only reason I can think of why they stay is because they are still convinced that one day they'll become famous. Twitter really seems to play on the idea that everyone can be a superstar. Sad really.
It boggles my mind that anyone, outside of the far-right lunatic fringe, is still on that platform. I left months before Elon Musk showed up, because they weren't doing enough to fight misinformation in 2020, and now it's an absolute dumpster fire. I can only guess there's something like the sunk cost fallacy at work here, and that's why people are reluctant to leave.
