Please read properly what you copy-pasted. “[…] via virtual communities and networks” (Friend and follower (and so on) relations create these virtual communities and networks, these don't exist on HN.) Ergo, HN is not social media. Facebook is social media, Twitter is social media. IRC is not, HN is not. Tiktok is, SnapChat is. Reddit isn't, Slashdot isn't. Google+ was, Orkut was. LWN isn't, Ars Technica isn't. Social media implies a massive global social graph which under-girds the communication flows – not rooms, forums, articles, channels, "subreddits", spaces, etc.
