One of the effects of this change will be that random voting will have the same apr as manual curation. Which could be a good thing or not (depending on what lense you are using to view it).

On the one hand it can inventivize voting on non popular authors since the opportunity cost of NOT front-running big votes will disappear.

On the other hand voting on low quality content will have the same earning potential as high quality pieces (from the curators point of view). So anyone can setup a bot and vote on anything.

Of course there is a small risk of losing curation rewards if what you are voting on gets downvoted but that can easily be countered by filtering for authors with a minimum reputation score.

EDIT: Also voting on comments will have the same apr as voting on posts...oh and get ready for comment farming.
