I've long since forgotten (if I ever *really* understood) how slashdot ranks their commentary, but it seems to be effective. Anything like their system at play in Snip? Years ago - that time seems to have passed - you could see MD surgeons, physicists, etc commenting on the validity and accuracy of posted article content. (not that MD's, for example, can't disagree on any given treatment protocol or Rx)
Edit - added: Can you differentiate your concept from Brave browser/content preference and payment system? I've seen your (dev) remarks regarding Steemit...
