Yahoo announced it will disregard "Do Not Track" settings and profile users anyway.

"Do Not Track" does not really mean users are not tracked. Sites that honor that system agree to limit how they use the tracking data, but they do not stop collecting it, so it does nothing to reduce the dossiers available for Big Brother to view at will. Thus, I have mostly not paid attention to Do Not Track.

However, this defiance by Yahoo might heat up the surveillance battle.
