I think people in hacker community are always way too afraid of where privacy is going. We should all understand, it's gone already. Facebook's remarketing is same as Google + Bing. Notice all those Tigerdirect ads. Personally I like ads on sites. They tend to be related content and helps site owners monetize. I think the conversation shouldn't be best way to stop cookie tracking but how to control what you want out there in a single place. It's really crappy to have to worry about privacy settings on hundreds of websites. I don't want to use the web on privacy mode.
