That is a common opinion I've seen these days, @kevinwong was writing about something similar in a post this week. I agree. Although earlier my opinion as an author was that curation rewards would be painful to "eat the loss" on, now I recognize that if we don't have the best possible curation, the value of being a good author is not properly recognized.
Maybe curation and authorship should be 50/50...
50/50 sounds about right. The whole platform pretty much rests on the shoulders of the curators, so it makes sense to offer them adequate compensation.
