Agreed. This is something someone might find useful in a project they're working on. Unlike any Techcrunch or Gruber post.

If HN were my personal pet project, that would be my link litmus test. "Is this something that might be useful info for making something, and not just 'news' to jabber on about?"

Might be too restrictive at first blush, but that is what I come here for, not to read "news" stories that are posted everywhere else too.
