Tell us how you really feel
I do mostly agree with you. I'll share with everybody how I generally approach social media.
First, I do share major family milestones, so my distant blood relatives can stay in touch - particularly appreciated over the past 11 months.
Second, I do most of my group/social organizational activities through social media (hikes, skis, bike rides, kayaking trips) and/or Strava (it considers itself a social media platform for athletes). Nothing against Trips & Events here, but I limit my invites to people I have vetted - those I trust to get me and/or help me get my dog out of the woods in an emergency.
Third, I find it useful for, and partipate by contributing to, crowdsourced information such as conditions, openings, closures, etc., for the above activities.
Fourth, There are occasional newsy items that interest me that may not appear in normal channels, such as cycling legislation at the state level, fishing legislation, quota changes, openings/closings, etc.
Fifth, There is some advantage to using it as one-stop shopping place for trusted pages ("liked pages") and relevant announcements - things like National Forests, Fish and Game, National Marine Fisheries, and various professional/educational announcements, like new product releases from Amazon Web Services, or my own employer. Oh, and musical interests (also a great source of entertainment during the pandemic), sports annoucements and highlights, etc.
It helps to remember that you really aren't the customer of most social media sites (paid or not) but rather the product. Have you noticed over the last 10 years or so you cannot purchase very many things online anymore as an anonymous user? Everyone wants your data for marketing purposes.
I would say that this site does qualify as social media, in some form. Nobody is required or encourage to use their real name, although some do. The platform offers "Friends" and "Likes" (disabled) and private groups (not used much if at all) and many other social-media inspired features.
