> I think how whuffie was described here seems like something that will really exist and I don’t know if there were any sites displaying cumulative karma for people.
The book was written when slashdot.org was really big, it basically invented the "Karma" system. There was this idea of user generated and curated content being a bright happy new future, and DAOITMK basically shot that idea dead by showing all the faults such a system would have. Of course subsequent sites (re: reddit) have exhibited all of those flaws. HN stays reasonable because of the mods, but even so the culture is a lot different here than it was 10 years ago. When I first created an account here short comments almost always got downvoted, posters who didn't have anything substantial learned to stay quiet.
(The downside of that culture is people learned to type intelligent sounding long form fluff!)
