I see what you're getting at, but eh, I'm not entirely convinced. What is a social network? I think there's some gray area there. The Wikipedia article you shared calls out Social Media as being "Web 2.0" (which itself is a nebulous term). One could argue that HN is just a forum, not unlike news groups that predated Web 2.0. Like I said: I see what you're getting at, and maybe HN is social media, but I would still assert that when considered as social media, HN is a far cry from a network like Facebook in terms of platform-functionality/feature-set/behavior/agenda.
