I have an extended family and also an extended circle of friends that are spread all over the world. In both cases, numbering dozens of people, what would have previously been a slow erosion of contact and any real knowledge about most of them except those absolutely closest to me by necessity, has been converted into the ability to keep abreast of their daily lives, know when some direct communication might be helpful and generally take joy in being able to see how the good things in their lives move forward (or offer a hand when they don't). All of this almost entirely thanks to social media.
This not to mention the interesting figures it lets me directly follow and the shared interest groups it lets me find.
Is social media a complex and vast thing with its many pitfalls and flaws? Of course it is. The corporate giants that run much of it have some very disgusting habits of passive aggressive manipulation of their users, and grossly parasitic dark patterns of surveillance behavior.
Nonetheless, under and around all of that, there's also a tremendous amount of practical human good being created by so much previously impossible connection between millions of family members, friends, loved ones and people who share things in common. I refuse to throw that baby out with the bath water as some seem to propose.
Political manipulation, factionalism and ideological bickering have always been a part of human culture, for at least as long as we've had written words and means of spreading them. Could anyone have expected any differently to emerge from the massively democratizing landscape of social platforms, which let literally anyone communicate their own two cents of thought to places and context where anyone else at all might instantly see them and respond? Of course not, but to focus only on that is almost elitist in its implied notions of shutting up the masses because they don't communicate and debate "correctly" (even if many of them are indeed stupidly influenced by all kinds of interests, whithin and outside of social media).
