I just shut down the last thing I was self-hosting: "Gandalf" - my trusty home server running in our living room book shelf. Over the years it has hosted, among other things, my personal web page, my OwnCloud/nextCloud and last my pump.io server. It was a Mac mini (from my old freedom-hating days π) running Debian GNU/Linux.
It's now two months since I deleted my Facebook and Twitter accounts. I can't say that I've missed them so far. Mostly it's a sense of relief that I don't have to think about if I should check my feed or not. On one occasion a friend wanted to tag me on a photo in Facebook and complained that it wasn't possible. I was quite happy with not being tagged βΊ
