Otherwise, I wouldn't be reading the news, I'd be reading the olds.
I check Hacker News often enough during a day that if I only care about the most upvoted articles, I reach a point in the list where the items that I've already read and the ones I haven't get mixed. Sorting by new, the moment I see something I've read before, I go "Ah, no more news."
If I'm particularly craving, I scroll down past the chunk of most recently read to a point in the past where there was a larger gap.
Because I spend too much time on here and exhaust the front page material.
(I'm not bitter about never getting a post to the front page...)
The internet never sleeps, but the content aggregator sites don't acknowledge it. I wish they treated submissions posted in the last 24 hours as equally fresh.
IMVHO that's why modern scoring is bad: the good scoring must be personal, like reading news (usenet) with personal scoring, saving things that interest you for future analysis and to pass them summarized to third parties wishing to learn.
That aspect is often ignored by many but we aren't (unfortunately) the Borg, we are a society, but not "a collective" witch means we can't pass knowledge directly and any of us have metabolized just a certain part of human knowledge, that's why mere scoring "following a collective recommendation engine" does work a bit but not as good as a similar personal engine.
After scanning/browsing the first 2-3 pages, there's no point in looking any further. Might as well look at new.
Plus, a vote on a post in /new is has a lot more impact than a vote on a post on the front page.
https://news.ycombinator.com/best and https://news.ycombinator.com/active are two other good pages that highlights stuff I missed from both the front and new page.
For long time I used Hckrnews with top 50% option, but I was still missing some content interesting for me. https://hckrnews.com
Few weeks ago I switched to Serializer (just HN option) synchronized between PC/mobile and I am happy with my choice, I see much more posts, but not all new + I can easily mark those I checked as read. https://serializer.io
Once a day I check also top 24h submissions here, if I haven't overlooked something: http://besthackernews.herokuapp.com/
