honestly I would love social networks that was just that but as it is now i actively avoid most social media outside of small niche communities (certain subreddits that relate to fairly narrow interest fan communities for a couple of authors that sort of thing [i don't fallow any default subs], hacker news, and a couple of small discord servers for open source projects and small podcasts)
but everything for talking to friends and family and keeping up on there lives is either been turned into a politically toxic battleground or monetized into unusability.
When I used FB, I used it as a non-professional LinkedIn. Like, networking, but for people outside of your professional network.
Being connected to people who are not so close that you shared your cell number, but still wanted to stay connected.
(Email isn't big where I live)
It is banal, at least the largest portion of social media is. Originally, I could see the usefulness of FB with connecting with friends near & far, sharing, planning, etc. All sounds useful, but then FB turned it creepy with their method of monetizing their products and algos to pull the strings to make it as addicting as possible. Insta, TikTok, etc has pretty much fully embraced the dark side of social. LOOK AT ME!!! LIKE ME!!! FOLLOW ME!!! Again, with the tweaking of the algos to up the addiction factor. All in the name of "engagement".
YouTube already made me nervous, but there's definitely some people creating content there that is not about that at all so I don't lump them in with the others.
