It starts with something silly like an avatar or profile pic next to every comment. If you'ld have had a flag or a dogpic or so next to your name/comment, I wouldn't have read your comment in the same relatively neutral way. I dislike the persona stuff, it's why I prefer forums. Lemmy is a collection of forums to me. I profoundly distrust persona cult stuff, like influencers etc. Sure, I'll encounter same people here I'm sure, but frankly: I'm mostly unaware, usernames barely register in my mind.

The part about social media I dislike is the real connection between Irl and online, and the "profile"-focus, for now both is no issue for me on lemmy.

I don't think the definition needs to be stretched very far. In any of such cases, the function is social, it is about connecting people and enabling them to communicate in a wider, multilateral fashion, online. However asocial we might convince ourselves of being, if we truly had no interest in it, we wouldn't even be discussing anything here.

Even lurkers, at the very least, place trust on a group to bring them matters which they are interested in, and if you consider it, this is the manner in which Reddit and forums are most similar to following influencers. The only difference is that it is a crowd-driven highlight, rather than an individual one, and even then people don't tend to follow just one single influencer.
