No, I don't think so. Not in the sense that social media became defined. Web forum, and bbs rooms, existed long before the term. The key difference and turning point was removal of anonymity, and the concept of self promotion. I know they are similar and overlap, but the evolution from one to the other did occur. Reddit and Lemmy still have more in common with news aggregation and forums than say a Titter, Instagram, Facebook, or TikTok. Most of the content here is in reference to something else, end then discussion are on that.

nah. Social Media has a sort of implied entertainment attached to it, which is not a good description of, e.g., this very discussion. This -can- be social media if you're just lurking, but for us conversing here this is now a forum. We're sharing thoughts and discussing.
