Well, i mean in short, that this is democracy, and we all know that total democracy is a failure. If it was natural in our world we would all be out voted by flies and had to eat shit.
If anything like this, then allow only Devs to vote anonym votes. If the suggestion helps them or not helps them. In meaning, if it gives them another view on subjective/alternative solution/constructive whining/idea that gives them new point of view maybe. If you dont agree, then explain what means "Good", and what means "Bad", if you suceed in explaining that, then i will agree to it.
