I agree with the OP.

I think of PM sort of like a virtual programming shop. If someone from another department walks in to my office and asks a basic Perl question, I answer it. This is true even if the save someone asks the same question every six months. Same goes here. Sometimes my answer is to hand them a book, but if so, I'll open it to the right page and give a few pointers before sending them off to read the fine manual.
