Mildly on topic: I recently moved to France from Canada, I'm not an EU citizen, and google isn't really sure if I'm on vacation or if I've moved permanently.
Every single website now asks me about cookie settings. Most have a reject all button, but occasionally I have to manually uncheck some sliders to protect my data. Time well spent.
My parents back in Canada always think it's some voodoo magic when Facebook shows them ads about stuff they've recently been 'talking about (AKA searching on Google.) Duhhh. Thanks EU!
