direct flash is something I noticed too when watching US President's speeches and press conferences. not that I am saying it is something that should be done however, I think it is more of how you control the light and the camera settings. I am not defending the photog or claiming he may have done a great job however, given a set of tools, it all comes down on how a person uses them (given the skill).
It is indeed intriguing on what the results are...I wonder if we could somehow see the wedding photog's work. I too am not a fan of direct flash but if I have no choice (no ceiling and wall to bounce, using bounce card would yield not much of a difference), direct flash would be my last resort.
