Decaying votes please and I love your idea to be able to vote negatively on a proposal.
We also need to find a way to keep the HPS system in front of our eyes. Like they say, "out of sight, out of mind."
The current structure of the HPS and Hive in general defaults as an Oligarchy and definitely needs an overhaul.
If a good new system isn't worked out soon, Hive is not on the path towards decentralization. I truly hope to see more topics addressing governance and project funding going forward.
