Yes and no :
I understand, that "new" is a bucket where everything goes to.
Then, in the header, there is a link to "show". When you go to this, there's a headline "you can browse the newest show here". That links to to site you've linked too.
So kind of "it's obvious" :)
But still a good find.
Did you know that new Show HN posts go to /shownew, not /show, and will stay on /shownew until they get a few (maybe 1, I'm not sure) upvotes. I learned this a few weeks ago.
