If there is no evidence of a real problem, and fixing the "problem" would not effectively improve Wikipedia, then don't waste time and energy (yours or anybody else's) 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.
