PageRank was a huge leap in knowing which web pages were valuable.<p>I&#x27;m disappointed we don&#x27;t have something similar for detecting authority, and measuring the opinions of those with authority.<p>For instance, if there were an article about chess, I would trust Bobby Fischer and Gary Kasparov to provide the most valuable commentary.  If they say it&#x27;s great, I&#x27;m more likely to read it.<p>But if there&#x27;s an article about Jewish business owners, I don&#x27;t want to see Bobby Fischer&#x27;s opinion.<p>If there&#x27;s an article about the government providing welfare and social services, I don&#x27;t want to see Kasparov&#x27;s opinion.<p>How is this not a thing for science, technology, news...?<p>&quot;This technology article should scare you!&quot;  If I see that from Linus Torvalds, it&#x27;s going to get my attention.  From John McAfee?  Not so much.<p>&quot;Nvidia&#x27;s latest drivers are terrible.&quot;  If that&#x27;s from AnimeFan2004, I don&#x27;t care.  If it&#x27;s from John Carmack, holy crap does it deserve my attention.<p>More importantly, if John Carmack trusts someone about computer graphics, I&#x27;ll probably trust them, too.  If they trust someone else about computer graphics, there&#x27;s a good chance I will, too.<p>We&#x27;ve gotten used to seeking out the opinion of Rotten Tomatoes, or the old Siskel and Ebert thumb-based-metric...  It&#x27;s a shame we don&#x27;t have a browser extension that brings those metrics to everything we see on the web.<p>I&#x27;m watching the trailer for the new Marvel Civil War movie...  and I see a Pop-Up-Video style bubble informing me that Kevin Smith really liked it.<p>I&#x27;m reading an article about how Facebook is bringing internet, but not really internet, to India, and I see EFF crapping all over it.  Right there - right on that same web page, because my browser extension brings that content in for me.<p>I&#x27;m reading an arxiv about gene transfer in plants, and I see experts in the field saying they question the methodology.<p>It just sucks to me that we don&#x27;t have a PageRank for authority on topics...  And we don&#x27;t have a way to show those scores and opinions, THAT WE TRUST, stuck to the content.<p>For instance, I trust Al Gore on Climate Change.  Other people probably trust Donald Trump on Climate Change.  It needs to be per-user to determine their authority-trust links.<p>Or helping determine our news feed.  (To finally relate my comments back to the topic at hand.)
