I am mostly peeved because I have to go and make manual changes to over 40 sites now, because I originally thought that the privacy of cookies were in the hands of the user. I have a P3P policy in place on all my sites so users know what they are opting in for when reading it, however this new law specify that I must ask permission from visitors in order to use cookies. This effects conversions, banner advertising and creates user frustration, simply because the law wasn't thought through clearly. I am not a happy camper.
