I get that, but the point is that I accidentally clicked No because instinctively I thought that was the way to dismiss the bar (in my mind it was something like: do you want to provide feedback yes/no, to which I clicked no). Only after clicking I realized my error.
@Avalaxy, it would be great when you click Yes or No, that you also try to add a comment about your issue or why you liked the page. I can not speak for every group, but most groups I know of review the voting and comments for all of their pages really carefully. For example, my team has a weekly discussion on this and what we plan to do to improve the pages. If a page gets a negative vote along with a comment why it poor, it is much easier to improve the page, however, if it simply has a negative vote we have to make guesses as to why it was poor.
