Maybe the parent is lamenting how some people post a lot of interesting scientific content, but also a whole lot of other content on topics that they are not interested in, and unfortunately most social networks require following all aspects of a person and not just the parts that interest you.

Google+ had it right where you can follow just a community, and also you can selectively make your participation in certain communities visible in your public profile. I am not sure if Bluesky or Mastodon have something similar.
