It's obviously subjective. The limit dolphin / whale doesn't really matter. The problem is that high-quality content gets downvoted without good reasons. That will hurt the steemit reputation badly !
The reason is to give more power to ppl who didn't invest time nor money in Steem. I just don't see how it's going to help us.

Helicopter Money or Rewards Driven is the Question?

I keep seeing posts on Steemit where people believe that the community should be throwing Steem at new users of the platform to get them to stick around. This idea makes me cringe! So you are telling me that we should literally be bribing people to use the platform? How does that work out in the real world? What kind of community would Steemit be if we set this precedent?
