I agree and do not think that model of advertising is a bad thing at all. It is something I find valuable as a user. I think that Marco is more complaining about how the advertising company in question figures out that you are you at that IP address and computer combination. It's the back end analytics they employ that is building and refining a database of people that continually use their products, of which the users either can't see, access and review, or are ignorant of in the first place. Being helpless is something we all fear as humans, and not having any say as to what kind of information may be in that database scares some people. Is it something that we all should be aware of? Probably. Should it keep us up at night? Probably not. +1 or Google+ helps them refine who they think we are, but really, they don't care who any of us are individually, they care about what will interest us next.
