I went the whole hog and deleted that fuck awful social media platform in 2018. It took about two days to get over it. Then some strange stuff happened - people who genuinely wanted to know what I was up to either e-mailed, texted or called - and lots of people dropped out of my life and I never spoke to them again.
It was refreshing and fucking excellent on every level. Facebook doesn't pay me for my writing, Medium does. I am not THAT interested in other people's lives, just other people's thoughts.
You want to really go on a cull, cull the whole platform. You won't regret it for a second.
