I’m late to this but I wanted to say that I’m glad to see this concern on LW. I have a tendency to burn out whenever I try to do things in The Most Efficient Way (precisely because my Efficient (TM) parts underestimate how much downtime other parts of me need), and I’ve had to avoid LW sometimes in order to get out of a “must do everything efficiently!” spiral.
(That said, I like this idea and will be trying it out and see if it helps or hurts me.)
ETA: I did not try it out after all; I was too worried about causing burnout.
My good:bad ratio was 1:2.75, which is a reason to use Facebook less for me (1:3 was “I’d rather not put up with that”, 1:1 was “would be okay”). This is after unfollowing lots of people. (In this exercise I also found two more people to unfollow.) I’ve hidden my newsfeed using F.B. Purity for now.
