No stripe.com URL boost = you'll have to work the hard way.
Whoa. There is absolutely no stripe.com URL boost, or any other kind of URL boost. The stellar.org post set off HN's voting ring detector. Edit: I (perhaps mistakenly) assumed the parent meant that HN itself was boosting certain URLs, as opposed to, say, name-recognition by users. The latter kind of thing is no doubt a factor.
Parent may have just meant an organic boost--I certainly notice submissions from certain domains above others, and from the looks of things it appears that others do, too. Not necessarily a bad thing at all, but it does seem to be an observable effect.

My understanding of the detector is that (among other things, presumably) it applies a penalty when visitors follow a link directly to the submission from a page other than "new", "news", etc. Is it possible that there is a bug (at least, I think it would be a bug) by which it also penalizes submissions where the visitor has followed a link from elsewhere on HN (eg. parent's link)? I followed the link and upvoted the story, and I assume several others used that path as well.
