I don't think the quality of discussion about social media suffers from lack of specification. Whether or not you consider HN to be social media, or wherever your decision boundary is, doesn't change that most of the conversation does apply to the general class of apps/websites that have become de-facto short form video platforms. Which lots of people use, so the effects of use are consequential and worth discussing.

The conversations on consciousness though...oh man. I have to steel myself before diving into that mess.
