I can say that a good social experience is usually in a very small group, dynamic, immersive, thrilling, you can feel it in your entire body, you loose your sense of time. On some social media the interactions are relatively slow, shallow, fragmented, in some sense performative because you know potentially alot of people can read what you're posting. It's like a totally different kind of social, which of course can have it's value but it becomes a problem when most of our social interactions are like this.
Take the experience of sharing your vacation pictures. On social media it is like you are packaging your memory to present for a broader audience. Imagine, in contrast, how you would invite your friend over and share your (printed) pictures over a coffee. Depending on what your relationship looks like you will present your trip differently. This shared memory will be woven into your relationship in a unique way, giving it yet another layer.
It's like the word social has been hijacked. It was never about making a "social media". It was about changing our idea about what social means..
