I'd struggle to place Discord, HN and possibly Reddit into the "social media" category. They sure aren't dead websites and they sure have a community, but they don't feel the same way as Facebook, Twitter and TikTok. Maybe it's the lack of name recognition that makes them feel different.

Discord definitely falls under the “social networking” category, but can definitely used as a social media platform.

The rest is certainly social media.

The difference essentially,

Social media: broadcast a message, share news, showcase your stuff and get people to interact with it: Facebook, insta, tiktok, reddit, HN - not necessarily two-way

Social networking: engage in two-way communication with similar minded people
