Just wanted to say I really like your two-stage voting idea.
The first could be gamed by an account having many bots, like some angry whales I know.
The second could be gamed by having a lot of SP -- again, like that angry whale.
So, the angry whale could game both of those voting configurations. However, very few are whales with many accounts. (Or, am I wrong here? Do most whales create extra accounts? I really don't know...)
Anyway, my examples weren't meant to be so pessimistic -- the first round is "one man, one vote" and the second round distributes funding based on weighted votes.
I think an addition to your idea would be: the only accounts eligible to vote in the second round, are accounts which had cast votes in the first round.
It still wouldn't keep the angry whale from benefiting; he could use his bot army on the first round, and then use the same army (and their SP) for the second round.
Perhaps a third round, to vote on the voters, but again, it seems the only two criteria are "number of votes" vs. "weight of votes" -- I can't think of a third method.
Well, perhaps multiplying by the account's reputation (with some weighting; perhaps, 1/10th of rep) might help, but again, whales with bot armies who have been here a while have had ample time to get their army's rep up as well. No clear answer. I really like your idea though! :)
Thank you. It will be difficult to make any voting system here perfect and immune from exploitation / gaming but at least a two stage system might allow for some corrections if needed.
