I would counter that a news site that allows comments on their posts is also social media under the guidelines that comments ipso facto makes it social media.
That's not a counter because it's arguing against a position that no-one is arguing for. I joined this thread to point out that the first post in it wasn't arguing for it. The distinction is staff content vs user content, not the existence of comments.
On Youtube OTOH, I seldom go to the comments other than a few woodworkers I follow and interact with personally.
My emphasis. And you don't consider that "social"? That's the pattern of use which defines social media.
Social media isn't about poltical trolling - although I don't doubt that for some people that makes up the majority of their experience with it. And a site/app doesn't cease to be social media because you personally choose not to interact with likes, comments, etc: it's about the pattern of use that it's designed to support.
If you can show me that what I wrote is off topic...
The only thing I said was that the "relaxed definition" you were objecting to was absent from and in contradiction with the post you replied to. Questions around what regulations websites should be subjected to are a completely separate issue to questions of how they should be categorised.
