In fact, I think targeted advertising can be win-win if it is done right. GMail does it right, and Facebook is getting better.
And a $100 billion valuation? I don't claim to know much about valuations, but this can't be serious.
Also, most of my profile is made up anyway. I have put cereals as one of my interests; I can't wait to receive 'contextual' cereal ads!
How would you have valued Google before Adsense and Adwords proved themselves?
