The Whole universe operates under a system of evolution that is based on improvement through feedback.
The feedback mechanism is different for different entities of the universe.

We know about the evolution of life through Darwin's theory.

Natural selection - the process on which the Darwin theory of evolution is based, illustrates the automatic feedback system that drives the evolution. 

The process of Natural selection holds that
"As random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival.These beneficial mutations are passed on to the next generation. Over time, beneficial mutations accumulate and the result is an entirely different organism (not just a variation of the original, but an entirely different creature)."

The beneficial mutations are the improvement feedback that aids evolution.

Our Site also needs feedback for improvement in its evolutionary path, least will it cease to be revolutionary..!
Unfortunately, Unlike God's creations, the creations of humans do not have such an automatic mechanism in place. So we had to devise one for our site.
