This idea more or less surfaces in the book "Fall; or, Dodge in Hell", where in the not-too-distant future the internet is so polluted that you are pretty much expected to hire a full-time "editor" to curate your social media feed.

Meanwhile the masses typically subscribe to an "off the shelf" stream (or several?) that most closely matches their tastes.
