I agree with your words but what will be the use of internet if it does not run the ads. No one will blog because there are no ads, why people will invest their time and get nothing in return. So I am in the favor of ads system. Even youtube will collapse soon if it stops displaying the ads. Ads are all important, they also make us aware of the new services, products or policies of the big companies in the world. It is only by the ads we come across new companies.
