I quit, and I found myself lost when I picked up my phone, like a lingering habit (I see someone mentioned it being similar to quitting smoking).
On reflection, I think the reason I felt an obligation to keep up with social issues etc, was because I was using my real name (ironic that this HN account is also my real name!). I felt like I had to show I was caring and keeping track of it. I do wonder, if I create an account without my real name, I can just use it how I like, and maybe it will be a different experience.
