I don't care about the "visual noise" of normal/banner-type ads - the real problem are those fucking layer ads with confusing icons (the X is the left one, the maximize button the right one), so if you want to read the content, first find out which type of layer ad it is, try to spot the 2x2px hotzone for the close button and THEN read the content.
People install adblockers because too many idiots became too fucking greedy and ruined ads for everyone else!
