cnn.com - I think that this is a good idea but in a way an invasion of privacy.
Of course it's an invasion of privacy...they want every viewer of every video...not just those related to Viacom. They are reaching well outside their rights and totally dismissing ours in the process.
P.S. - I posted this yesterday :-P
What agravates me most about this is if Google/You Tube would have given this information out freely then they would be sued for violating users rights to privacy, but a judge can step in and make a blanket ruling and they have to do exactly the thing that if they did do they'd be in trouble for to. I think I confused myself there.
