Being a webmaster, I feel that its our right to earn small amount of money off visitors who use our serveries or resources. but now a days many people are using ad-blocking software to blogs or remove ads being displayed, whether it is a banner or popups. Now so many sites depend on this advertisement revenue to continue the basis of their site; they give something to the community and have to pay for the web hosting someway, and often this is through advertising, and people are using the site, and not providing an impression let alone a click on the banners.
