Adsense, pour une publicité plus efficace

I've just recieved an email this morning, about the new Adsense feature (the ad system by google) that will be: advertising according to the visitor's interest. Good principe, it'll make ads more efficient.

The principe is the following: google will keep in memory the sites/pages you see, aim to establish a profile of the visitor. For example, if google notices that you see lots of site about sport, the ads you see will tend to be related to sports. Before the ads were related to the theme of the site, now the ad is specially adapted to the visitor! It's a new kind of advertising that is much more efficient.

The bad point is that the visitors will suffer of a struggling watch. It's big brother.

The law will oblige the editor sites to mention that they're using this kind of ads.
