I used to use Facebook a lot. It knew me, always recommended stuff I'd be interested in and I sometimes spent hours on Facebook and not even realizing it, only after I finished and then I'd feel guilty about it. The same shit next day.
I quit all social media 3 years ago. I don't visit them daily anymore. I visit Facebook only with a purpose to check something specific when I need it in one of the groups (in my country reddit or Twitter is not popular, we have Facebook groups for everything) and I almost never check the feed. When I do I realize I changed so much in those three years Facebook no longer knows me and the stuff it recommends is not interesting anymore.
I don't miss any of it. Yeah, sometimes I don't get what colleagues are talking about, but it's not important. I have more time on my hands to do anything else.
