"how about a time limit on witness votes?"
Good point! Yeah, if votes are not limited by time, then over time they are most likely to stack up, giving some Witnesses virtually endless power and making them ever harder to vote out imo.
I will add that in an additional Witnesses section of this Hive5 project into v1.3 next week.
As for the unstake (power down) time period, the 3 weeks can definitely be increased. Let's meet at 6 weeks for now. It's rough, but let's give this one more time so that others have a chance to comment on the number of weeks they too feel a new unstake time would be ideal.
Thank you again Allen for your ideas! 💚💚
