Advertising is useful, at least until we find a better way to pay for things we don't want to pay for. Unfortunately, history has proven we also need ways to steer their behaviour. I don't particularly miss having metric tonnes of dead trees shoved through my front door. Or having my phone ring all evening. I don't think pop-up blockers have destroyed the internet as we know it. And I don't feel bad for any business model that's suffered from improvements in spam filtering. While it's obvious the money needed to run out favourite services needs to come from somewhere, it's also obvious that we need to be able to enforce some limits to the never-ending war to make your advert more visible than the other guy's.
