I barely post any more either because Facebook in particular has turned into a sewer of AI slop, local whinging and ads.
I think most people with any intelligence look back at their social media behaviour from a decade ago and cringe at themselves. I'm sure you're no worse than a lot of people. I never posted stuff like that but there was a period when I genuinely thought people might care what I'd had for lunch or that I'd just spotted a squirrel in my garden. Madness.
Honestly it's such a bizarre phenomenon, looking back on it. like a period of collective insanity. I think people who still post a lot on social media now (over the age of about 20) are a bit desperate.
I miss the ability to easily chat to friends I rarely see but I'm so glad its in decline.
