EDIT : I can not edit the post so I will put my comments here:
I was quite direct and critic with this post, but I have to admit that all users (whales and dolphins included) showed me they are not as bad as I thought.
They accepted my criticism and doubts and tried to listen to my objections.
So I can say now that Steemit is not so elitist as I thought, and maybe being a little rude was useful to wake up some people and start a constructive discussion about the future of the Community.
