In broad strokes, yeah. I’d even consider older, more traditional forms like forums and IRC/BBS to be proto forms of social media. As long as the internet exists there will be social media, what form it takes is malleable depending on the desires of the userbase at hand.

Yes but I’d classify it as a different category more akin to old school forums. It’s less a place to post photos of yourself and more one to discuss and read about stuff you enjoy (or memes). I just want a place personally to discuss movies, video games, technology etc
