Another approach to the “Voting nudge” would be, to register as a voter.
Of course, registration should not be tied to any requirements.
That way only the interested bakers/delegation-services would vote (and count for the Quorum).
Also Exchanges which can’t/doesn’t want to vote, wouldn’t influence the Quorum that way.
It could be seamlessly integrated in the current Voting process. The Proposal Phase could reset at the point a proposal is injected, to make sure it runs at least 5 cycles.
Everyone who participates in the Proposal Phase will be registered as a voter.
The Quorum in the Exploration/Promotion Phase would be calculated on the base of registered voters from the Proposal Phase.
The prerequisite for this is, that the proposal phase also has a yay/nay/pass option.
