I'm surprised.

By running adsense ads on Yahoo pages Google can now gather metrics from Yahoo and you know they are chomping at the bit to do so. Google will most likely adjust their knowledge graph and news offering using some of the data the collect from Yahoo, which is filled with content that they want to display too. This move doesn't feel well thought through by yahoo.
