How the votes taper could be adjusted, perhaps not each successive vote it could be at key values and reset at 30 minutes. I think the knock off benefit of this would be that people who curate as a whole don't just dogpile a "sure thing" and are encouraged to uncover other content. If they do dogpile, then the reward reduction will reflect the decreased amount of work (or risk) put in to uncover other gems. I think it solves two fundamental problems with enough flexibility.
