I think I get the general idea behind, but it made me wonder, how hard it is going to be to code a bot that will spot those posts with the beneficiaries set and vote only those posts for the max profit?
Remember that author can set the additional curators share to 0% :)
Continuing that line of thought.. it will open a new opportunity to those spammy and abusive accounts to get automated votes, just because the beneficiary is set.
We can downvote those too.
Why not extending the 5 min window?
Well, the 5 min windows doesn't mean that you should vote in those 5 minutes- quite the opposite. And yes, this will work like you mentioned, it's gonna be still worth to vote for old posts / posts that already get good reward. At least more than now.
They can. But lots will set higher too I bet, so averagely it will still be better than voting the old fashioned posts?
The problem is that a lot of people do vote in the 5 min. Also very big accounts vote in that time. So if I vote later, my curation rewards are going down and down... So I don't have to, but I kind of have to :)
