I'll play the devil's advocate and say that I'm actually disappointed by this development. A very long time ago when AdSense was young I was thrilled by the idea that instead of being bombarded by stupid ads designed to cater to morons people (including myself) will be getting relevant ads - ideally, ads about stuff that I am actually willing to buy right now. Kinda like legilimency. Too bad that this will be impossible for a long time to come now.
