Old or New Facebook, there are changes going on

There has been an ongoing debate among my geeky friends whether they hate or love the new Facebook. There is even a group petitioning for Facebook to go back to the old set up. I am one of those who are sitting in the neutral fence, not really caring, however I noticed an interesting additional feature in the ads application. Apparently if you click on the ads, you will be able to rate it whether you like or hate it, along with your feedback to the ads. As one of the advertising world denizen, I am quite intrigued by this functionality. After all, apart from occasional focus group, it is rather rare for us to get a feedback on our works, so you know, we can improve it ;-) Is this a wind of change for advertising world? Would this become the standard norm in the future?
