Unfortunately I have seen this film before (some experience on this). Normally the most knowledgeable people of the case/problem are the people actually being busy of doing it. When they start communicating with "PR" people that time is away from the work. And when you get the "PR" people to actually write the message and doing the communication to outside you get the messages people here is complaining (general message for all, cut'n'paste, ...).

That doesn't mean that I disagree with you here but what I'm saying is that it's not easy and it causes other problems.
