I don't like the concept of 'good' authors, I prefer the idea of upvoting good posts! :)
Upvoting 'good' authors automatically means being too lazy to read and evaluate posts, means allwoing 'good' authors to be lazy too, as they receive upvotes independently from the quality of their posts, means not giving 'bad' authors the incentive to improve and have the chance of receiving upvotes when writing better posts than before, means to keep ignoring new, unknown users which leave the platform as fast as they came, because nobody makes the effort to seek for posts manually.
I see not a single reason why I should get less curation rewards when manually upvoting a two days old post which I had really read and evaluated than someone who didn't work at all but just let a programm do the job!
