For what it’s worth, HN is already a bit like this.
Back when I lived in the ‘states, I’d wake up in the morning and participate in all sorts of interesting discussions on a bunch of fresh posts.
Now, living in Europe, I wake up to a homepage full of “7 hours ago” top comments with 200 points on them. Any contribution we make from here will last maybe a minute or two before getting sorted down out of view.
I spend most of my time now reading what y’all had to say about stuff.
