I'm catching up all around...
I know it's late, and everyone is scattering...
But in my opinions... the concept and framing of "social media" was engineered and developed specifically as a "model for control and monitoring." This was by design.
As with quite a number of these "social" developments... accompanies by a narrative... it is still often overlooked that these agencies (I won't call them businesses, because there success has everything to do with government sponsorship and collusion of banks) were caught red-handed in 'experiments and research' regarding the specific ways they can affect users emotionally and how to track them perpetually.
Everyone scoffed at the irony... these 'bastions of free speech' would have fit in well in certain historical regimes.
And alarmingly, in ours as well... (COVID anyone?)
They have demonstrated clearly... for all to see that they are NOT our friends... and most frequently... they are the source and well-spring of disinformation... and outright lies... empowered by 'undisclosed' sources.
All while demanding the "natural" right to curtail who says what and when... to "define" what is and isn't misinformation... as they spew it daily... in baser, more manipulative ways.... (the "mostly peaceful" destruction proclamation was amazingly dystopian.)
Social media is a natural communication venue because people are naturally "social."
It is possible to have a nominal social life... or even exceptional one... without a private communications medium in which to "participate socially."
I make no excuses, nor apologies....
COMMERCIAL interests cannot be simply believed when they define ANYTHING. "AI," "Social media", "vaccine," "Existential threats," "Social security," "Health care"... you name it - they've mangled the definition for commerce to exploit... and our government appears to cheer and 'help' every time.
When
they say social media they mean "$ for clicks" paradigm world... where "viral" is exploitable money... and bot's 'create' trends to custom order, and literally thousands of people exist to simply "change the metrics" everywhere they are assigned. Social media to them is the 'battleground' upon which they have the advantage over the ignorant.
When some around here use the term, the meaning can range from the cash cow industry... to a place where people can gather and exchange ideas...
The governments of the world have allowed the bank God to demand we all must exist in the 'internet world" to participate in their 'economic governing'... if you don't play... they don't pay.
So the "social media" thing is just another adjunct place they ultimately control... and suck data out of the system to "use".... give to 'special' friends to exploit.... (Used to be in the job of policing that slimy type of shit...

) now they use it as a secret currency... don't worry... they already blew the game (as they usually do) there's no notional 'winning' for them...
As for the presence one has on social media... I used to think that in many cases, people's "personas" online could be very misleading... a person can either be genuine... or 'attempt to be free to 'LARP' or 'experiment,' and in some cases 'fantasize' who they might be... in the safety of a 'no-direct-contact' kind of anonymity.
Facebook and it's many transnational clones... they are all the same tool... 'feeding' you the 'news' some 'algorithmic calculation' supposedly 'decides' you 'will like.' But few noted exactly how they 'valued' and 'monetized' your input... and proceed to use that data to "whisper" back.
It's all very 'serving the interface' gestalt stuff...
If you feel empty without the place and acquaintances of social media... you're normal.
If you discover a new peace descending upon you in it's absence... you are normal.
If you feel kind of 'empty' and 'loneliness' around the absence... you are normal.
It's not really about the medium... it's the social.
Sadly for the no-contact architects in training... there is always real life...
interestingly, I've heard these folks complain... how "it's just not fair..."
Our focus defines our reality and what value we can derive from it.
Sharing a space or time with others... that's social...
