I have also seen more than one of these redesigns for HN. I would love a new design. Current one is more like web brutalism. But this is not it.
You have made the layout more like an table, but for readers it is very, very important to know the source of article and meta data. I just think this is such an eyestrain to look left and right all the time.
I like that your solution is not so saturated as others. IMHO I would love something between your design and Kevin Granger’s (https://dribbble.com/shots/1879206-Hacker-News-Search-Experimental-Design) Oh, and there should be 30 results and “more” button. Once you hit it there is infinite scroll.
