I disagree... I find ads an extremely agreeable way for the web to run. I get what I want for free, you get money just simply because someone's ad showed up.

Sweet.

What I don't care for is the idea that one or two megacorps know everything about me. So I selectively use ad-block software to keep the Big Boys from overly tracking me.

I find your version of the future--in which ad networks are gone and content proviers stay around because they provide their services "just for giggles" or require micro+ payments--unpalatable.
