Fully agree. And more than that, I think you're objectively correct.

Think about the evolution of the term "social media". It evolved from social networks, which themselves evolved from forums.

The "media" in "social media" refers to third-party content that is algorithmically boosted through social signals, with signals from your own network weighting higher, and in the end creating a personalized algorithm of media content.

There is no personalized media on HN. It's the same feed for everyone. There is no network on HN. No friends, follows, private messages.

So there's no social to HN, and no (personalized) media, and no network.
