I don't know why you are downvoted, HN is a big part of my news addiction cycle, but I can't help it.
There is a certain satisfaction in reading news, being in the know about new developments - even if 80% of the time it doesn't help you at all/you'll forget about it the next day.
I'm wasting so much time on news sites and other pages that inform me about new developments, it's quite sad.
Most of the time there isn't even any news to be had - it's just "oh, nothing new here, moving on" in a cycle through different pages - then the thought lingers on that there might be something new by now and I start again from the beginning.
For this to work, there would have to be solidarity among the other platforms, all of them turning off on the same day (yes, even HN!)
But I can actually imagine the world's productivity boost on such a day.
