I don't think it is owned by PG or YC.
At least the from domain info, it is not very obvious.
I would be careful and not login to that domain with my HN credentials
I'm confused. Could the submitter or the creator of the site explain what the purpose of the link is? It simply looks like a reproduction of Hacker News, at a different URL.
Some guy registered the domain as a favor to the community. He submitted here and was flamed for the inherent security issues. It has remained in existence. http://news.ycombinator.com/item?id=84039
I mistyped hacker news earlier today and discovered this, so I thought I'd submit it.
