"Duplication" implies intentional copying…
I didn't mean intentional. Although I may use a wrong word. If so i want to apologize for it.
I even consider maybe authors didn't even know the other works exist, so much content is on site now.
But in my way of thinking if you making some form of art or any creation, about some ideas which allready been "explored" by someone before you, you have to make some distinctive qualities in performance or explore the idea in some new unexplored way or make a difference in any other way. Otherwise it would be "industrial mass production" or even "Chinese industrial mass production". Machines are good at it. And people in mass love good mass-produced product. Phones. Cars. Shoes.
Steady suply, steady quality.
For exemple:
The Black Square by Kazimir Malevich is world-famous pice of art. Black Circle, Red Square and a bunch of his own late works not known by the public at large not because they kept in secret.
Of course the main yardstick of art is the audience reception. And it's been the foundation guiding star, which lead this community to today prosperity.
But lately it somehow go soft. It began to tolerate more and more. Not in good sense.
Sometimes works wich would be downvoted in to oblivion a few years ago. (I want to make a note, what i dont imply this very one work).
Someone posted a scp which is literally "deathnote ink bottle" more then a year ago. With demonic scriming and other staff, not even written in good clinic tone. And it's still somethere here.
I mean no offense to you or the autors of any of mentioned work.
Discussion page is here so any one can discus any pice of work, and give the authors the feedback about what is good and what is bad from his point of view. Maybe for improvment of current work, maybe for later use and consideration.
How to use gotten feedback is totaly the authors choise. Even to read or not to read the feedback is each author own choise.
If some of them will see my point and will consider it for later works my feedback will have a reasult. If not, it would be a sign to me that world has changed.
