It upsets me that the "normal" way to keep in touch with people now seems to be to use some kind of big-brother-esque system. I try and evangelize Signal over WhatsApp and most of my friends won't budge. I deleted my Facebook four years ago, and as a result I have lost contact with a lot of friends.
That there is this artificial world where people can arbitrarily keep in contact doesn't make that sort of non-interaction of occasionally commenting on or liking posts normal or better. It certainly is easy though to search for someone you knew ages ago, add a friend, have the five minute conversation of what's been going on the last five, ten, twenty years and then never really talk again.
In this regard facebook isn't the problem, and your preferred platform isn't a solution. The problem is people.
