X is excellent for following niche research interests but they’ve been pushing quite hard to force political news/opinions into the feeds which is really annoying.
It's run by a guy who literally did a nazi salute. One of their most prolific users is named "catturd". I'm astonished that anybody in research or science still remains there.
Edit to add: The owner of the platform contributed millions of dollars, endorsements, and manipulation of the platform to elect a regime which actively works to dismantle scientific and research funding and institutions. By continuing to use the platform, these people are contributing to the destruction of their work and careers.
