"European Union laws require you to give European Union visitors information about cookies used on your blog. In many cases, these laws also require you to obtain consent.
As a courtesy, we have added a notice on your blog to explain Google's use of certain Blogger and Google cookies, including use of Google Analytics and AdSense cookies.
You are responsible for confirming this notice actually works for your blog, and that it displays. If you employ other cookies, for example by adding third party features, this notice may not work for you."
OK, I'm hereby giving any European Union friends who visit this blog notice that I have no control over any cookies that are set on this blog. The notice mentioned above was not apparent on this blog when I looked a few minutes ago. And I do not "employ other cookies, for example by adding third party features."
So I will say that if the EU friends who visit this site don't want to consent to whatever cookies Google uses, they should either not visit this site OR get Ghostery, which blocks Google Analytics, AdSense and most other "trackers." You should note that some trackers have to be enabled for you to use certain aspects on websites (like playing media files). You can whitelist sites or pages so Ghostery will not block their trackers, so it's not an "all or nothing" kind of thing.
