HN is much more like an RSS feed of interesting articles, where people can leave comments -- there is some back and forth (as in this case) but not a lot; it's centered around the linked content and thoughts on that content, not on engaging with other users. It's not monetized and therefore doesn't employ all the tricks that SM uses to "drive engagement", which is often driven by outrage (which is therefore a highly desirable component of a SM).
I like technology. I like making things I love and others can enjoy. I like when others make something they think is cool and love and enjoy and I can enjoy them too.
That's why this place is dope. I can't press 'Share' so that's not social media to me.
