Yes, please. The current system gives voters power without accountability and it needs to be changed. A voter can abuse authority in the last 12 hours with no impact upon his or her reputation, while authors have no recourse and can have both their reputations and payouts impacted. This 12 hour lockout period was well intentioned to prevent author sniping abuse, but instead has left us wide open to voting abuse. A better system would be the one Smooth suggested, in which (if I understand correctly) votes decline in % strength during the last 12 hours, so that any vote can be up/down countered with minimal deterioration of value, and any last-minute vote sniping would be nearly worthless.
