Copied from my recent post. Not entering the contest, I'd want someone else to win it.
Minute 0 voting should be allowed. Arbitrarily soft-preventing someone from voting on a new post or comment they enjoy is terrible, period.
Curation rewards should always be a fixed percentage and independent of the time the vote is cast.
Curation rewards should be higher, possibly around 50% or so. Don't encourage or force the largest vested accounts to also spam us with posts. Let them simply vote to generate ROI, to punish human curation less as opposed to self-voting or vote-selling.
Curation rewards should have identical payout options as author rewards. Do not advantage one over the other with SBD/SP/STEEM payout options unavailable to the other. This is a no-brainer.
No increase or decrease in curation rewards based on the voting order. Coming late to the party should not be so terrible for voters if they want to reward an older post.
The new sub-15 minute curation pool is garbage. Remove the option to auto-vote on post creation if you're really going to do this, as it's disingenuous to leave it as-is without a huge blinking red disclaimer attached.
This is the best place to start.
I really fail to see where they even got the time order voting idea from, it should have been obvious to anyone that it was a terrible idea from the start.
