It will be increasingly difficult to reward a good comments all by yourself, though, without risking that vote to eventually be lost as dust.
I'm thinking about upvotes on posts as well as comments. With my SP, any upvote I give has to be at 70% minimum or else it will fall into the "dust" threshold and be swept-away when rewards are paid-out. If the price of Steem falls, then a higher-percentage would be required; if the price of Steem rises, then that percentage will fall and perhaps a 50% upvote will no longer count as dust, as it will now.
BTW, Bunny has mutual support now...
Maybe there's a little misunderstanding?!
This dust-rule we're dealing with here applies to combined rewards, so two 1-cent-votes would still make sure there's enough rewards to not be dust and it will be paid out. This is exactly where the bunny comes in, it will upvote just as much on top of the existing rewards as what's needed to bring them over the dust-limit (with a generous safety margin) at least 12 hours before payout.
During the last 12 hours before payout, voting efficiency decreases, so anything that's not fluffed up by the bunny at that point, that means the bunny didn't get to it.
But, there's actually a dust-vote policy as well... before HF20 the blockchain completely rejected votes if they were too small. Since HF20 this has been changed by reducing all votes by 50million rshares (that's maybe 1.5SP?!), smaller votes will be treated as actual dust-voytes with zero rshares. This has nothing to do with the bunny's purpose, though.
