The people who complain about how things work are the people who make things better. If everyone was satisfied with jQuery and felt that JS development could stop after that then we wouldn't be where we are today, and if everybody thinks that where we are now is fine then tomorrow will look exactly the same as today. I, for one, want tomorow to look different (and better) regardless of how rosy it looks today, so I will continue complaining. When I can, I will also do something about my complaints, and I do submit patches when I can, but unfortunately thats not always feasible.
