Essentially a reputation system, based on publisher or specific known authors then?
How would, say, something like Thompson's "Trusting Trust" (though I suppose that was published in ACM or IEEE), or a Dijkstra or Pike blog post, rate?
Comments from, say, Linus Torvalds on the LKML, or Lennert Pottering on systemd, or Bill Gates' various book recommendations, etc.?
Something like this could filter out the "random geek wanna-be with an axe to grind" type post.
