I quit Facebook right around the time my son was born. It wasn't for privacy reasons (and frankly, it never bothered me), but rather for the enormous energy and time sink it had become. Truly, it was as if I was a dopamine junkie and Facebook was the pusher of those sweet, sweet red circles with a number in them that meant someone, somewhere vaguely agreed with something you posted. I noticed I was not present in the…
Most of my "real" friends seemed to have stopped posting on there, yet I was still addicted to scrolling through the feed while waiting for code to compile or whatever (clever design on their part, I guess!).
However, also like you, the privacy side doesn't worry me too much (although as time goes by I do start to think about it more), and I still get some value from communicating with certain people on FB Messenger and being able to access photos from events etc., so instead of quitting, I unfollowed everyone (using a bit of Javascript - I'll try and dig it out).
My feed is now totally blank, so I now only visit maybe twice a day for a few seconds to check for messages (I refuse to install their app - mbasic.facebook.com all the way!). I did think I could refollow people if I felt I was missing out, but surprise surprise, I don't at all.
Of course, I've now replaced reading Facebook with reading Twitter while stuff compiles but at least that's relevant to my work ;)
I'd highly recommend this approach if you feel uncomfortable with your use of Facebook but also value your network of friends on there.
