Dear whoever decides how websites of various medium-big sized corps work:

I came to your goddamn website to find information. Not to fill out a stupid survey. And, if you had taken the trouble to track me with nasty little cookies, you would have seen that I've never visited your site before, so how the heck could I have any feedback whatsoever to give you?

If I wanted to take surveys, I would have registered an account with Yougov and spend the whole bloody day telling them how many tooth paste ads I've read in the last decade.
