alt Hacker News> with the aim of being as succinct but high quality as possible
You're assuming "high karma = high quality" which, isn't always correct :) I've had wildly incorrect claims be upvoted a lot, and correct ones downvoted, seems to be more about what the subject is about and what "side you're coming from" rather than anything else sometimes. Other times it goes exactly as expected.
End effect is, I wouldn't rely on karma as a signal for quality, just "agreement at large" or something.
No, I mentioned in the grandparent comment:
> Although karma points are not equivalent to quality,
But I don't think they are totally uncorrelated to quality, either. So you'd need a way to factor karma points in without over-valuing them.
To really get specific, the only thing we're really measuring here is something like, well-written, succinct comments that are appreciated by HN users that are able to upvote. Which is not exactly super useful or insightful, but is a fun exercise.
