Facebook is what you make of it. If you filter out the content like politics and news aspect of it then it’s still a useful tool for staying in touch with friends and family. I quite enjoy seeing what some of my friends have been up to from afar but wouldn’t ring them up randomly for a conversation. My feed is just what I want to see and I never understand why people don’t customise it. It’s like saying ‘all the people I follow on Twitter post boring content’. It’s very easy to rectify. Then again I’m not interested in convincing anybody I don’t know as it really doesn’t matter.
What you are doing is basically stalking. FB is a stalking tool. "Ohh my ex girlfriend with whom I haven talked to in 10 years has renovated her kitchen, let's have a look shall we". Do you make sure to post stuff on regular basis about your life so others kan "see what you are up to from afar"? Or are you just silently lurking in the background?
Anyway - yes it is technically possible to limit your facebook to 10 people and filter out all the bad stuff (all thought FB will bombard you with "people you may know" with creepy accuracy plus endless suggestions - but thats not how most people use it. Plus you get addicted, the point is to get addicted to it, to feel stuff, engage, click, like, lecture, humble brag, curate a faux online persona, get jealous of others, make people jealous of you, etc.
Yeah i dont like it at all. And you know what - I used to love it and frown at people who refused it once.
