I know it's weird but here has been my ANALOG solution to HN information consumption and even to tab overload (a chronic incurable autoimmune disease I acquired when just leaving my teens, during college life, which may have impeded my growth).
I write much, sci-fi and always draft some articles (but never publish), so that keeping up with HN is a sort of reference material building activity, other than it I don't go on twitter, IG, reddit, slack, mastodon or whatever IRC channel, so I try to make the most of my constrained addiction, but it's always tough work to clean up a browser tab accumulation, as the Feynman quote quips, it's costly, you have to pay attention:
The method involves a paper notebook, which I use whenever I can in lieu of a PC for drafting, taking notes, planning etc. On a two-page spread I start sth like an index by arbitrary useful topics of my current researches. Each line is a one or two word topic, after the word I simply list the HN IDs separated by comma. It's nice to save individual comment threads or whole posts using the same interface. When useful I write a little two word note on top of the number. In this fashion I close dozens or hundreds of tabs and postpone/defer reading the interesting conversations to when I will take action upon it e.g. by writing a short story or poetry or articles. I also use the GTD golden 2-min rule: if I can read and/or take action on a useful discussion or link posted in a few minutes, I do it on the spot and close the HN post forever. Done.
