The losing a higher percentage of VP when voting on higher rewarded posts sounds like an elegant solution, but wouldn't this serve a 'redistribution function' more effectively if it was combined with linear rather than exponential rewards?
Even if the CEO of Stinc isn't listening ATM, it's still useful to work through the alternatives in case he ever does, or for contributing to alternative platforms... this is still only a test after all!
No I think linear rewards have proven to create the wrong incentives for everybody. As suggested by @jaki01, something in which starts out linear and gradually becomes exponential is probably best. But I think we would all appreciate one change at a time so that we can properly evaluate the results before moving forward.
