That is definitely a potential downside, but that is all relative. It will seem like a loss to authors since they are used to 75% rewards, but if you look at it from the perspective of what they would get on other sites which have no rewards at all 50% is pretty big.
Also one of my thoughts is that by offering 50% to curators it could potentially get more votes for good content than with 25% curation rewards making it potentially a net gain for authors. Remains to be seen if that would actually happen though.
Thank you very much for your support!
Agree that authors would gain back from increased curator reward. Will be interesting to see if there is a change and how it would effect the whole. I have no idea of the politics here and what it would take to have such a change put in place. Guess it would need a majority of witnesses to have the power to effect the change?
