I think I did something similar. I decided to severely control my information diet after November and switch to only RSS feeds that I have selected manually and HN. It’s gone better than I expected and I feel very little urge to go back.
At the same time, I’m definitely less informed. Though I’m quite surprised how much still permeates despite me not “going looking”.
Generally, I think it’s more healthy to focus on what you can control and what you have agency over. You can choose what to be outraged over national/global events (and do nothing) or you can instead focus that energy on Doing Something closer to home that’s important to you. Which is the better trade?
I’m somewhat conflicted on being less informed esp with big changes happening. And even more conflicted about what kind of world we’d have if everyone chose this strategy. But, it’s not unprincipled. The principle is Focus on What You Can Control/Do and put all your energy into that.
