> HN is social media

I haven't posted any personal pics, or stories about things that I've done in my life or am currently doing, so how can it be social in the same way that social media is? To me, there's a clear distinction between a news aggregator and discussion forum like HN, and a social media site. Sure, I can post something that I'm working on or a blog post that I've written, but it's still framed as news to be discussed, not a social interaction.
