I had a friend in college who was very good at quitting smoking. Every weekend, she would smoke at parties, and every Monday, she would quit smoking once again.
For me, quitting Twitter was more like Hemmingway’s going broke: slowly then all at once.
Slowly, I created a professional account, moved the alt account using my teenage AIM screen name to private, and juggled which devices (laptop, phone, tablet) were able to access which accounts under which screen names at which times with what screen time limits. And then all at once I stopped reading any of my Tweeter feeds, thanks pretty much entirely due to reading the first two chapters of The This by Adam Roberts.
