Spoiler alert: this article is not about make-up, traveling, introducing myself or a meme.
In my opinion, Steemit reward system should be revised because...let us imagine for a moment, what if a group of "whales" wants to highlight a specific news or a couple of news favorable to them (especially for elections candidates) they will just upvote the post...and the post will be in top 10 for sure. As we all aware, Steemit gives a great opportunity to promote info's.
And at some point, Steemit may become the no. 1 social-media. Mass media is the most powerful tool used by the ruling class to manipulate the masses. It shapes and molds opinions and attitudes and defines what is normal and acceptable. Most of the "whales" here, as in any business, are present just to make profit and go (hit & run).
But on the other hand, "whales" are not necessary "bad"..they can be good and supportive (see the 
“...people live their lives bound by what they accept as correct and true... that is how they define reality. But what does it mean to be correct or true? Merely vague concepts... their reality may all be an illusion.”
For the moment, let's just be happy than any article (more or less meaningless) can be in the top 10.
