I understand your points regarding the rewards pool. Ned is already considering Ads, he's weighing the options available. You probably wouldn't know though, not having Ads was one of Steemit's unique selling point that set it apart from other social networks when it was launched. If they are to back on that, there'll be adverse effects.
How much of your earning are you willing to part with?
I used Utopian.io while they were taking 25% as beneficiary rewards. I wouldn't mind a cut from my rewards.
We both want what is best for the platform, but hold contrary views.
