What I propose is: willing whales to vote - that is to say one who wish to commit the time and effort explained in details here should be able to do so.
Additionally in order to "not harm the whales" say 10% of each current account vests can be put in/converted to Curation Power at the beginning - this way whales interested in active curation will have a good head start but still reduced dominance compared to the current destructive IMHO levels.
