Social media emerged as a term to describe Facebook and MySpace, places where you added connections between friends and shared moments of your life with them, not a comment section on a website. Using the term “social media” to describe something that existed before those sites existed devalues the actual worth of forums as a meeting place. There is clearly a difference between something like Twitter and Facebook who’s only purpose is to show you ads and things to get you angry using algorithms and places like Lemmy and really any sort of comment section (Reddit and 4chan included) that are simply people talking to each other.

I would expect most people here would be able to understand the difference and how referring to things that are distinctly not Facebook or Twitter as being in the same category. Reddit, Lemmy, your random double edge razor forum, etc are not social media. They’re forums. They’ve existed for thousands of years.
