I havn't read the post yet but I clicked on it because I assumed it was a blog post by heroku, it's interesting that it links to a redirect to another url, I'm sure this is just an honest mistake but I wonder if someone has tested if things like google.com (for google pages) heroku.com (heroku apps) and other premium domains fair better with HN because of the official nature.

I also wonder how that would be affected if HN started showing the subdomain of the url as well.
