Wikipedia:If it ain't broke, don't fix it
 | This is an essay. It contains the advice or opinions of one or more Wikipedia contributors. This page is not an encyclopedia article, nor is it one of Wikipedia's policies or guidelines, as it has not been thoroughly vetted by the community. Some essays represent widespread norms; others only represent minority viewpoints. |
If there is no evidence of a real problem, and fixing the "problem" would not effectively improve Wikipedia, then don't waste your or other editors' time and energy trying to fix it.
On the other hand, if something is slightly broken in a way that you care about, and fixing it improves the encyclopedia a little, then feel free to fix it.
