I presume the front-page algorithm has some sort of "magic" in it so that the only articles making it to the front page are that which a significant proportion of the user base would want there. Is that not correct?
Not every post is going to be interesting everyone, but as I mentioned before, the originating URL makes it easy to spot ones from URL's you know that you're not interested in.
Myself, I am a bit of an apple fanboy - and seeing what other HN-ers opinions are on Grubers posts does interest me. I think there are probably a fair few apple fanboys on HN who agree with me.
On a similar, but unrelated note, most (not all) of the articles I read on HN I've already seen through some other means anyway. It's really only the comments that I'm interested in, which are generally of vastly superior quality than that of the originating site (if it has them).
edit: at the time of writing, the story does only have 8 votes. Is HN using popularity of previous stories from that domain to push it to the front page quicker? It does seem a little odd - maybe I'm wrong, and the users of HN really don't care about this story anymore.
