On Hacker News, the ask and show pages are implemented just like the front page, but they filter the item list based on title or whether or not there's a link.
And yes, that means they won't show items not already loaded into RAM ;)
Thx, i had found this [1], but what i really need is a toptable/topic like https://news.ycombinator.com/show (which is diff from 'about' page. (A story whose title begins with "Show HN" goes to /show. FYI [2]))
