Can you provide examples of what a stupid question is?
The PM's job is to communicate the project status with stakeholders. In my experience even the developers who are really good at this only do as well as a mediocre project manager. Their job is to pick out any risks or crises and mitigate them before they derail the project. If you are working with a great project manager your life as a developer gets much easier. Granted, if your project manager isn't on the ball, your in for a not fun time.
