The reduction of the early voting penalty should be the easiest to pass since it isn’t very controversial and it would be an easy change.
The variable curation/author split that which can be set by the individual platforms (or even the users), rather than being hardcoded to 75/25 seems like a really interesting idea too. There are details in @jesta’s reply to the recent steemitblog post. I wonder if we can rally support around that.
Yes, clearly the latter is a more significant change in terms of implementation, maybe controversial, hard to say. But yes, very interesting idea. Overall I agree with your assessment.
