I quit Facebook initially because of notification spam. However I discovered something afterwards. I had less negative feelings toward family and friends. I had unconsciously been forming an opinion of them that was based on the habits Facebook was encouraging rather than their actual personality.
In a sense I'm a lot happier not knowing that Great Aunt Gertrude shared that post. And most of the time Aunt Gertrude didn't even think about what she was sharing so the opinion wasn't based in fact.
I just never read the wall thingy. When I go to FB, it's either directly to the messenger or to facebook.com/<my username>. I really only use it for the IM. I hate how it's 2017 and it doesn't have simple things like bold* or colors, that were available in AIM/MSN/Yahoo/EveryotherMessenger before (not to mention until the early 2010s, FB message was the most unreliable piece of garbage in the world. If you used Pidgin/Audium/anything XMPP, half the time messages wouldn't get through).
I have too many friends spread across the world to ever quit FB, but I only really use it for messages. I only post things if they promote my website and pull people to my content and away from Facebook. Since that's all I do, my posts obviously don't get as much reach. It's kinda the opposite of the Silent Bob effect. You have a friend who always says crap and you ignore them. If someone says things only once a week; you pay attention when they have something to say.
Facebook basically penalizes people who only speak when they have something important to say and rewards people who cannot learn to shut the hell up.
*I realize it has bold now, but it doesn't work universally across all their tools: mobile, web, etc. I know people who just use unicode symbols for italics because it's more reliable.
To me it resembles that condo mailbox, filled with spam and colorful leaflets I know I don't need so pick them up and dump them annoyed into the trash box provided for my convenience and everyone's right next to it. Once a week I end up on Facebook for a few seconds, check to see if someone left some important message, and if not quickly leave the screaming place. For all those needy souls of relatives and acquaintances I instructed my twitter to automatically repost on facebook, which is rare but at least gives them something to feed upon.
