This would be a public HN comment evaluation and verification engine in the browser. One could go so far as to build a website based on the concept, consuming the HN comment firehose and scoring comments as they’re created, an append only transaction log of sorts. Comments are permanent after two hours, so you only have to run each comment through each model once if you wait until that expiration window passes.
“Computah, validate truthiness of all comments in this thread.”
(Bonus points for scoring HN users by how factually accurate they are over time from their comment history)
