Why Digg should ditch MSN and use Adsense

We all love digg. It keeps us updated about the latest happenings. But the advertisement on the Digg are painfully irrelevant.I clicked on this sony ad and I was taken to the page only to realise that it is for US residents. I don't understand why such ads are displayed in other countries.It is irritating to view such ads. On the other hand Adsense would generate the perfect ads.
