Turns out that a lot of people I knew posted huge life updates that I completely missed out on. I asked them why they didn’t tell me and they were confused. They said the posted it on social media. I can’t speak for everyone, but I know a lack of social media meant that I have lost touch with old acquaintances completely. I have a few close friends and that’s it.
Maybe that’s an ok tradeoff to make, but it’s worth knowing that before getting into it.
This doesn't really seem that important if your only method of knowing this was a post blasted to hundreds (or thousands) of people. Or, to put it another way: if you mattered, you would've gotten a direct message or call from them.
I'd argue that social media has normalized keeping up with people who aren't supposed to be part of your life forever. But, we should take a step back and realize that not everything should or will last forever. If you cross paths again then you can catch up, but having life updates constantly? No thanks.
The landscape of human relationships is deep and broad an varied, and if making bold assumptions about what other people should value is your starting point, you're liable to miss a lot of potential connections.
