> These pluralities are unable to exist on social media

I broadly agree with the author, but I have a small nit regarding the above sentence. Pluralities definitely are able to exist on social media, it's just that it is far easier to get swept up in sensationalism, outrage and gossip than it is to find and continue seeing sensible and well-thought posts. The initial days of social media enabled the former, but got drowned out when mass popularity was reached. Think early days Twitter and Quora.

I say this as a person who has no social media accounts, but uses twitter intermittently without an account. It is possible to find nice things on the internet using a pull-based model, i.e. when you actively search for (not just passively follow!) the good stuff and actively block out all the bad stuff. Problem is that SM companies make it increasingly difficult to do this, plus trusting your reading list to the "recommended" and "trending now" sections of a social media feed causes issues. But knowing for what to search and how yields good results which you would not be able to find if you have a blanket ban on anything social-related.

I think curation (of said pluralities) would be possible on social media (like it's possible for example on Wikipedia), but the interactions are effectively owned (controlled) by the media owner, and they don't necessarily want the participants to have that power.
