> "specialized ~creators~"

I can understand what this means in the context of visual platforms like Instagram and TikTok. (Slight quibble on TT in that a number of very large creators there record from their cars, kitchens, or otherwise do not employ specialized production.)

In any case, what does "specialized creators" mean in the context of (primarily) text-based platforms like Twitter, LinkedIn, and Facebook? Does that mean they are not social media?

On any platform that would be considered social media by any definition, popular posts serve as a place for people to interact with each other. They are more ephemeral than a subreddit, but they serve the same function.

I am honestly not trying to troll, I just don't understand the distinction.
