Wikipedia:Positivity

Positivity is a term popularized by journalist Albert Nerenberg to mean an emphasis on the positive in the face of the gloominess of the 21st Century. Nerenberg was surprised that officially, Positivity is not truly recognized as a word. The term was featured in a series published by the Montreal Gazette, which featured new trends in culture and science which emphasized hope, intelligence, and human progress in face of war, fear and climate change.

Wikipedia positivity is editors who add quality content on Wikipedia and make comments with quality and positive suggestions rather than empty negativity.

Time to complain
As in life, on WP:Wikipedia, if you don't have time to explain, you don't have time to complain. If you can't explain, you can't complain.

If you don't have grounds, don't make a fuss over nothing. If you don't have anything positive to add it seems highly irrational to add negativity to the environment. We all wish that things in this world or life where better, but I would rather fix a problem then hear someone say that something is wrong because it's wrong, or read someone say, "this article is crappy," without any positive suggestions.
