I think most people only recall becoming aware of Facebook when it was already so widespread that people talked about it as "the site you go to to find out what extended family members and people you haven't spoken to in years are up to".

Let's remember that the original idea was to connect with people in your college/university. I faintly recall this time period because I tried to sign up for it only to find out that while there had been an announcement that it was opened up internationally, it still only let you sign up with a dot EDU email address, which none of the universities in my country had.

In the early years "social media" was a lot more about having a place to express yourself or share your ideas and opinions so other people you know could check up on them. Many remember the GIF anarchy and crimes against HTML of Geocities but that aesthetic also carried over to MySpace while sites like Live Journal or Tumblr more heavily emphasized prose. This was all also in the context of a more open "blogosphere" where (mostly) tech nerds would run their own blogs and connect intentionally much like "webrings" did in the earlier days for private homepages and such before search engine indexing mostly obliterated their main use.

Facebook pretty much created modern "social media" by creating the global "timeline", forcing users to compete with each other (and corporate brands) for each other's attention while also focusing the experience more on consumption and "reaction" than creation and self-expression. This in turn resulted in more "engagement" which eventually led to algorithmic timelines trying to optimize for engagement and ad placement / "suggested content".

HN actually follows the "link aggregator" or "news aggregator" lineage of sites like Reddit, Digg, Fark, etc (there were also "bookmark aggregators" like stumbleupon but most of those died out to). In terms of social interactions it's more like e.g. the Slashdot comment section even though the "feed" is somewhat "engagement driven" like on social media sites. But as you said, it lacks all the features that would normally be expected like the ability to "curate" your timeline (or in fact, having a personalized view of the timeline at all) or being able to "follow" specific people. You can't even block people.
