Let the market decide, demand and supply

That's all we are doing.

Do you really think everyone should check if there's something similar out there before you post something? Seriously?

Don't play dumb. You and everyone is well aware that these same topics on Steemit rewards, who gets them, how to get them, etc. have been played and replayed for weeks and months. It is not something you need to go and check.

cut down the rewards for more than 280 voters

The problem with this argument is that most of reward didn't come from most of those 280 voters, it came from a relatively few with large influence. Live by the sword, die by the sword. It cuts both ways.

The reward algorithm is designed to produce the largest rewards when the subjective value of a post has consensus, meaning a large number of stake-weighted votes all agree it should be rewarded. I disagree, so there is no a high degree of consensus here, and the rewards are accordingly reduced.

Please post quality content on topics that add new value to Steemit instead of recycling the existing value of Steemit with more discussion of Steemit. I will happily upvote that and perhaps others will as well, bringing you high rewards.
