I've noticed that there are extremely diminishing returns here. You get 95% of the benefit of HN in the first 20 minutes of skimming the front page and commenting, and the rest of the time is significantly less beneficial. Thus, I try to only visit it once or twice a day for ten minutes or so, and have reply notification to comments set up.
How do you do that? That would probably cut my procrastination in half! HN used to be connected with some push notification startup and there was an option for it in profile, but it seems missing now.
