I quit Facebook around 6 years ago and it was So easy. Facebook is trash, the ui is trash, I mean it's ridiculous, and that was 6 years ago. I can't imagine how bad the ui is now, but it gives me a headache to try.
I can only imagine it must be likes, I've rarely gotten likes on any platform. I assume it is because I am writing what I can only assume is gibberish to others. This simple fact stopped me from being addicted.
Be less likeable and quitting social media is super easy. Just tell the truth, that seems to work great at reducing likes.
